5.10.2 - February 14, 2022

OmniSciDB - New Features and Improvements

• The COPY TO command now exports time, date, and timestamp data types in ISO 8601 format. Previously, date and timestamp data types were exported as unix epochs.

OmniSciDB - Fixed Issues

• Fixed crash that could occur when window function partitions were sorted on multiple columns.

• Fixed crash that could occur when in-situ queries had query step punted to CPU.

• Fixed crash that could occur when columnar output is forced for queries projecting variable length types, either by command-line flag or query hint.

OmniSci Render - Fixed Issues

• Fixes hit-testing issues in single-node elated to rendering SQL with aggregate subqueries. Such queries could be generated using the cohort feature in Immerse or using custom dimensions. Previously, you could see errors such as the following in map charts: Cannot find column <column name> in hit-test cache for query <sql query>. Most errors of that form should be resolved in single-node.

OmniSci Immerse - Fixed Issues

• Fixed New Combo Chart legend appearing over chart bars.

• Fixed 'Failed to Load Tables' error when navigating to the data manager.

5.10.1 - January 25, 2022

OmniSci Immerse - Fixed Issues

• Fixed issue where projections with more than 1M rows of geo and other variable-length types could crash the server when –columnar-large-projections is enabled.

• Fixed issue with rendering results of certain subqueries when running distributed.

• Fixed data manager error occuring when global custom expressions beta feature is enabled.

• Upgrade log4j to 2.17.1 to address CVE-2021-44832.

5.10.0 - January 10, 2022

The SAML Entitlement feature is deprecated and may be removed in a future release. Row-level security (RLS), with a role specified through SAML, provides an improved replacement.

OmniSciDB - New Features and Improvements

Administration

• Row-level security (RLS): Administrators can use new commands CREATE POLICY, SHOW POLICIES, and DROP POLICY to apply security filtering to queries run as a user or with a role.

Performance

• Significantly more performant, parallelized window functions, executing up to 10X faster than in Release 5.9.

• Automatic use of columnar output (instead of the default row-wise output) for large projections, particularly benefitting window functions, subqueries, and table function calls that returned large numbers of rows, lowering query times by 5-10X in some cases. The threshold defaults to 1M rows, but can be modified with thecolumnar-large-projections-threshold flag (and turned off with columnar-large-projections=false).

• UNION ALL now works with tables that do not share dictionary columns and supports query patterns such as grouped inputs. Previously only projections were supported.

• Large IN subqueries are now significantly faster and scalable by rewriting the associated query plans as decorrelated joins.

SQL Functionality

• Added support for full set of ST_TRANSFORM SRIDs supported by geos/proj4 library.

• Significant ST_DWithin speedups involving LINESTRING types via an optimization to clip the checked region of the LINESTRING to just the portion that can possibly fall within the specified distance of the other geometry.

• Removes a previous restriction where null values were not allowed for text array columns.

• Adds ANY_VALUE as canonical SQL alias for existing SAMPLE aggregate operator.

Geo Enhancements

• Support for full set of ST_TRANSFORM SRIDs supported by geos/proj4 library.

• High performance UTM transforms (ST_TRANSFORM) available to and from web mercator and geographic coordinate systems.

• Significant ST_DWithin speedups involving LINESTRING types via an optimization to clip the checked region of the LINESTRING to just the portion that can possibly fall within the specified distance of the other geometry.

Import Improvements

• Adds support for import from dozens of image and raster file types, such as jpeg, png, geotiff and ESRI grid, including remote files.

• Adds support for numerous vector GIS files (100+ formats supported by current GDAL release).

• Adds support for multidimensional array import from GRIB/GRIB2 formats common in science and meteorology.

When importing GRIB/GRIB2 raster files, the default multithreaded import behavior is unstable due to a bug in the GDAL library; this issue will be addressed in the next release. You must use the WITH option threads=1 to force single-threaded operation and avoid a server crash. This restriction does not apply to any other raster formats.

• Adds support for selected layers or bands within multilayer files.

• Adds a new flag to SQLImporter that allows narrowing of integer values.

• Improves point import speed regardless of source.

• Extended file metadata and column detection in omnisql to include additional formats.

OmniSciDB - Fixed Issues

• Fixes an issue in the ODBC driver where some SQL statements containing double quotes would result in an error.

• Fixes an issue where decimal value imports could fail, even when the specified number of maximum rejections has not been reached.

• Fixes a crash that occurs when the max rows option is set for an empty table.

OmniSci Render - Fixed Issues

• Fixes a potential ghosting artifact when rendering consecutive accumulation renders in a multi-gpu system using the OpenGL driver.

OmniSci Immerse - New Features and Improvements

• Fixed custom SQL expression support for custom data sources.

• Fixed various cases for upgrading legacy charts to the New Combo chart.

• Fixed various minor UI issues.

5.9.0 - November 18, 2021

OmniSciDB - New Features and Improvements

• Adds IF EXISTS support to DROP USER and DROP ROLE statements.

• Significant speedup for POINT and fixed-length array imports and CTAS/ITAS--generally 5-20X faster.

OmniSciDB - Fixed Issues

• Fixes an issue where null values and empty arrays were not imported correctly for text array columns.

• Correctly account for compressed size of 8-bit and 16-bit dictionary encoded text columns and all geo type columns to avoid overly aggressive punting of queries to CPU when columns of these types are used in a query.

• Prevent overflow of columns with widths less than 4 bytes when columnar projection used in a query, which could lead to a crash.

OmniSci Render - New Features and Improvements

• Improves the performance of density accumulation stats gathering when using min/max/1stStdDev/2ndStdDev ranges, up to 50x speedups in some instances.

• The PNG encoding step of a render request is no longer a blocking step, thereby improving render concurrency.

OmniSci Render - Fixed Issues

• Fixes a potential timeout in the Vulkan renderer in a multi-GPU server configuration if GPU contention caused by many queries/renders executing at the same time exists. The timeout can manifest as a VulkanDeviceLost error that can lock up renders for a minute before the renderer can recover.

• Fixes a minor memory leak when caching parsed Vega JSONs.

• Fixes a possible ghosting artifact in multilayer/multi-GPU renders when individual layers use different subsets of available GPUs when rendered.

5.8.1 - November 9, 2021

OmniSciDB - New Features

• Added a new SHOW ROLES command for viewing directly assigned and effective user roles.

OmniSci Render - Fixed Issues

• Fixed a regression in Release 5.8.0 where purging idle render sessions can result in server crashes with the OpenGL renderer.

• Fixes a regression in Release 5.8.0 where poly renders can result in segfaults.

OmniSci Immerse - Fixed Issues

• User role checks that block dashboard load and login are completed much more quickly.

5.8.0 - October 11, 2021

Release 5.8 officially enables the new Vulkan backend renderer as the default, replacing the OpenGL renderer. For more information on Vulkan, reasons for the change, and troubleshooting, see Vulkan Renderer.

The legacy OpenGL backend renderer is still available as a fallback, but will be deprecated and removed in subsequent releases, so it is advisable to use the legacy OpenGL renderer only if you have a blocking issue with Vulkan. To disable the Vulkan renderer and enable OpenGL, add the following flag to your server configuration:

renderer-use-vulkan-driver=false

In distributed clusters, the configuration file for each node must have this parameter set to use OpenGL.

Releases 5.7 and higher require the installation of a Vulkan API loader library to support the Vulkan renderer. This library is required regardless of whether you are using the Vulkan renderer or not. If you are upgrading from Release 5.7, you have already installed this library and no further action is required.

If you see an error similar to the following when trying to start a renderer-enabled Release 5.8 server for the first time, you need to install the Vulkan API loader:

error while loading shared libraries: libvulkan.so.1: cannot open shared object file: No such file or directory

To install the Vulkan API loader:

• On CentOS: sudo yum install vulkan

• On Ubuntu: sudo apt install libvulkan1

For a summary of how to install the Vulkan loader on other various Linux distributions, see https://linuxconfig.org/install-and-test-vulkan-on-linux.

For other troubleshooting issues, see Vulkan Renderer.

OmniSciDB - New Features and Improvements

• Parallel executors now on by default (with default --num-executors=2)

• Spatial joins between point types using ST_Distance type are now accelerated using overlaps join hash framework, with increased in speed up to 100x.

• Window functions can run on empty partitions and can operate over tables with multiple fragments and shards.

• Queries that need to run a query step on CPU due to memory pressure or compatibility reasons now execute only that individual step on CPU. Previously, the full query was restarted and all steps ran on CPU.

• Support WIDTH_BUCKET operator for easier numeric binning.

• Natively support ST_Transform to/from all UTM zones and EPSG:4326 (Lon/Lat) and EPSG:900913 (Web Mercator).

• Support provided for file path regex filter and for file path sort order when running the COPY FROM command.

• New ALTER SYSTEM CLEAR commands enable clearing CPU or GPU memory.

• Error messages for DUMP/RESTORE commands are improved.

• Validations and error messages are improved when specifying default column values.

• More robust handling is added for long decimal strings during import.

• Non-superusers can view and interrupt their own queries.

• Rewrote query plans where certain aggregates are performed on the same expression that is grouped-by (that is, COUNT DISTINCT column where column is being grouped) to improve performance for these queries

OmniSciDB - Fixed Issues

• Fixed an issue where window functions with a preceding filter would pull all of a table’s columns into memory, even if unused by the query.

• Disabled window functions for updates because it could crash the server. Targeted to be fixed and enabled in a future release.

• Various fixes related to aggregate window functions.

• Improvements to auto-casting logic for extension functions, user-defined row functions, and table functions.

• Avoid unnecessary translation between dictionary-encoded text columns for certain classes of hash joins when the inner and outer tables’ join columns share the same dictionary, thereby improving performance.

• Fixed crash that could occur when performing a join on multifragment input when the hash table is built on GPU but the join is executed on CPU.

• Various bug fixes and performance improvements for runtime query interrupt.

• Fixed broken Immerse dashboard import in omnisql.

OmniSci Rendering - New Features and Improvements

• The default renderer is now Vulkan. The legacy OpenGL renderer can still be used as a fallback. See the notice at the top of these release notes for more information.

• Improved the memory footprint/performance of the multi-GPU compositor by doing overlapped, tiled transfers from render GPUs to the compositor GPU. The more GPUs on the node, the bigger potential gains.

• Added extra logging in the event of a timeout or Vulkan device lost error.

OmniSci Immerse - New Features

• Migrated numeric binning in Immerse to use the new WIDTH_BUCKET SQL operator, significantly improving binning/histogram performance in some cases.

• Fixed role retrieval for usernames with @ and other symbols ($ & + , ; : / = ?).

5.7.0 - August 26, 2021

OmniSciDB - New Features and Improvements

Query Capabilities

• Added support for default column values. When creating tables or adding new columns to existing tables, you can now specify column default values. This works in both SQL and with Thrift APIs.

• Added support for APPROX_QUANTILE, with performance and functionality similar to APPROX_MEDIAN, which is APPROX_QUANTILE called with a 50% quantile argument.

• Per-kernel interrupt performance significantly improved, now on by default. Queries can be interrupted using Ctrl + C in omnisql, or by calling the interrupt API.

Performance

• The Arrow data frame API now differentiates between where the query is run and where the Arrow result is requested. For example, a query that must run on CPU can be pushed to GPU for Arrow IPC sharing, and a query that would normally run on GPU can still run on GPU, even if the user requests the Arrow buffer in CPU memory via IPC sharing.

• Improved performance of high-cardinality group-by queries. Large cohorts in Immerse should show substantial performance improvement.

• Parallel executors now in public beta (set with --num-executors flag). In future versions of OmniSci, the number of executors will be set to 2 by default.

Administrative

• Added a new REASSIGN OWNED command, which changes ownership of database objects (tables, views, dashboards, etc.) from a user or set of users in the current database to a different user.

• Added a new SHOW USER DETAILS command for introspecting user information.

• Error messages have been updated to remove redundancy and otherwise extraneous content.

Geospatial

• Added support to ST_Transform for transformations from 900913 (web mercator) to 4326 (lon/lat).

• ST_Contains and ST_Intersect joins and filters can now run fully accelerated on dynamically constructed points using ST_Point(lon, lat).

• Geospatial projection support for points is now more robust, faster, and widely supported. For example, ST_SetSRID(ST_Point(id,id),4326) is now supported in projections.

• Major enhancements to ODBC driver, including support for Geospatial types.

• Added FlatGeoBuf import/export support, which is about 3x faster than shapefile and 8x faster than geojson.

• Improved handling of geospatial columns in intermediate results and temporary tables. Previously, a "columnar conversion not supported" error would be thrown in joins involving multi-fragment geospatial tables. Now, the geospatial column can be zipped up, allowing joins and similar operations to proceed.

Enhanced AWS Permissions and Session Management

• Added support for using IAM roles or server permissions when importing data from AWS S3. Admins can enable the use of IAM roles when running on an EC2 instance. Credentials can also be configured on the server either through AWS environment variables or credential files. Enable this option with the allow-s3-server-privileges server configuration.

• Added support for AWS session tokens through omnisql and Thrift import APIs.

OmniSciDB - Fixed Issues

• Improved messaging related to an error that can occur when the sample data insert script downloads data to a path outside the server data directory.

• Fixed an issue where the server can encounter an error on startup due to a pre 4.0 release migration bug.

• Fixed a race condition that can occur when SELECT queries and auto-vacuuming execute concurrently.

• Projections without limits now should not re-compile if query literals change, significantly increasing performance

• Arrow over-the-wire query requests were always being executed on CPU, now they will run on default device type (and can be overridden by the user with a query hint)

• Fix crash that could occur with empty Arrow result sets

• omnisql now returns error status codes if a single command is called and the command fails. This allows omnisql to be more easily embedded into scripts with error checking.

• Resolved an issue where join table reordering could fail for some geojoins, resulting in an error message or crash.

• Resolved a crash that occurred when inserting a NULL value into a geospatial column in distributed mode.

• Various bug fixes and performance improvements for geospatial types in Insert Into As Select / Create Table As Select queries in distributed mode.

• Resolved a crash that occurred when updating a BOOLEAN array column.

• Resolved null handling issues when grouping by BIGINT columns.

• Resolved an issue which prevented CURRENT_TIME() or NOW() from being used in aggregate queries.

• Resolved an issue involving CASE statements with string literals in one of the case branches, where the returned results could be incorrect.

• Comparison between full array and indexed array columns will throw an appropriate error. Previously, SQL with such a comparison could cause the server to crash.

• Resolved an issue where NULLS LAST in an ORDER BY clause could cause an incorrect ordering with respect to sign (e.g. negatives before positives).

• Resolved an issue where CTAS/ITAS queries with small returns in the SELECT statement could enter an infinite loop in distributed mode.

• Resolved an issue preventing the owner of a database from dropping that database.

OmniSci Rendering - New Features and Improvements

Release 5.7 includes the official beta release of the new Vulkan-backed renderer, which will replace the current OpenGL renderer. For more information, see Vulkan and the reasons we are making the switch, see Vulkan Renderer (Beta).

Because Vulkan will be the default renderer in Release 5.8, OmniSci strongly recommends using it now. The OpenGL renderer will be deprecated and removed in subsequent releases. The Vulkan renderer is reliable and stable, and switching to Vulkan now can help reveal any unforeseen issues. Finding such issues early, while an easy fallback exists, ensures a smooth, less risky transition.

To enable the beta Vulkan renderer, set the renderer-use-vulkan-driver configuration parameter to true.

In distributed clusters, the configuration file for each node must have the parameter set.

The Vulkan library is required for Release 5.7, regardless of which renderer you use. If you do not install the renderer, you will see the following error when trying to start a renderer-enabled server for the first time:

error while loading shared libraries: libvulkan.so.1: cannot open shared object file: No such file or directory

If you receive this error, you need to install the Vulkan API loader:

• CentOS: sudo yum install vulkan

• Ubuntu: sudo apt install libvulkan1

For a summary of how to install the Vulkan loader on various Linux distributions, see: https://linuxconfig.org/install-and-test-vulkan-on-linux.

• Significant speedups in large polygon renders across multiple GPUs. The larger the table, and the more GPUs, the bigger the speed increase.

• Memory footprint improvements in compositing and anti-aliasing components.

• 3-4x speedup with procedural rendering (i.e. “symbol” vega mark type)

• Better pipelining of compressed geo columns and projection math; 2x memory footprint improvement in use cases

• Added a new Airplane symbol shape for Vega that can be used in symbol/legacy symbol marks.

OmniSci Immerse - New Features and Improvements

• Significant enhancements to Immerse parameters.

  • Dashboard parameter widgets:

    • Side-panel parameter controllers can be added to dashboards.

    • Supports sophisticated custom dashboards with no code required.

  • Parameter value display across the product:

    • Chart titles and chart axes labels

    • Dashboard titles

    • Tooltips and Legends

  • Convenience methods to use parameters within:

    • Chart column selectors

• High-precision, higher-performance lasso tool:

  • Now uses an ST_Contains filter expression for drawn polygons instead of expensive inside-triangle expressions.

  • Employs a dynamic level-of-detail drawing algorithm that automatically adjusts the resolution of parts of a polygon/circle that are in view so that it matches the results of the ST_Contains filter exactly for map charts.

• 3D Pointmap chart (Beta release).

• Embed HTML in a text chart (Beta release).

• Updated mapd-connector with latest version of Thrift.

• Duplication of charts with an empty filter is now allowed.

5.6.0 - April 21, 2021

OmniSci release 5.6.0 contains several new features and improvements and fixes a number of issues.

OmniSciDB

New Features and Improvements

• Allowed import and export paths are now enforced. Confirm that any import or export paths are included via the configuration parameters allowed-export-paths and allowed-import-paths.

• Loading data now more strictly enforces validation or numeric inputs. Previously, an out-of-range integer would “wrap” and be ingested as incorrect values. In Release 5.6, numerics are validated and if validation fails, the row is rejected.

• String dictionaries do not load if you exceed their capacities; previously, they inserted null for the string.

• Utility jar mapd-1.0-SNAPSHOT-jar-with-dependencies.jar is renamed. Scripts using SQLimporter need to reference the new .jar omnisci-utility-5.6.0.jar.

• Significant speedups for point-in-polygon joins (ST_CONTAINS, ST_INTERSECTS) via optimized algorithms and range join hash framework; on by default for point-in-polygon joins.

• Approximate median function support through the new approx_median aggregate function. Currently works only in nondistributed deployments and executes on CPU.

• Query interrupt is now possible when the query is outside of core kernel execution (for example, copy/import, CTAS, ITAS, query data fetch, result reduction). On by default and controlled by new flag enable-non-kernel-time-query-interrupt.

• Query interrupt during core kernel execution has been optimized so that enabling it with the existing enable-runtime-query-interrupt flag should have little to no impact on query performance; actual impact depends on the query pattern.

• Added partial column specification for INSERT and INSERT FROM SELECT, such that data can be inserted and appended to a subset of columns in a table. NULL values are added to columns not specified in the statements.

• Updated the CREATE TABLE command max_rollback_epochs option with a default value of 3. This reduces the number of epochs/data versions that are stored. When combined with new space reclamation on delete, optimizes space utilization. Setting the option with a high value stores more epochs and reduces data compaction and space reclamation. To update older tables, use the ALTER TABLE <table> SET MAX_ROLLBACK_EPOCHS=<value> command.

• Added automatic metadata updates and vacuuming. On UPDATE and DELETE queries, OmniSciDB updates metadata, vacuums, and re-uses space as specified. Automatic metadata updates are turned on by default. See enable-auto-metadata-update in Configuration Parameters. Automatic vacuuming on delete occurs when deletes or updates on variable length columns exceed the vacuum threshold. For more information, see vacuum-min-selectivity in Configuration Parameters.

To ensure optimal space usage, ensure the table’s MAX_ROLLBACK_EPOCHS option is set to 3 or lower. This is automatically set by default for the CREATE TABLE command on new tables created in release 5.6 and higher.

For existing databases, OmniSci recommends using ALTER TABLE <table> SET MAX_ROLLBACK_EPOCHS=3 to cap the space usage, and OPTIMIZE TABLE [<table>] WITH (VACUUM='true'); to reclaim space. This primes the system for efficient space management.

• Added RENAME TABLE command to enable one or more tables to be renamed at the same time.

• OmniSciDB now enforces permitted filepaths for import/export operations by default. The default import and export paths ({data directory}/map_import and {data directory}/map_export respectively) are allowed by default, so no change is required when doing an import/export from Immerse or for sample data import on server startup. However, when using other commands with user-provided paths (such as COPY FROM) provided paths must be under an allowed root path. See the Configuration Parameters for more information.

  NOTE: For distributed systems, allowed paths only need to be in the configuration file on the aggregator. However, for consistency and future compatibility, OmniSci recommends that the allowed paths also be added to the leaf omnisci.conf file.

• Significantly improved OmniSciDB startup time. Removed extra metadata seeks/reads during startup. Systems with high epoch counts or large column counts will have marked improvements.

• Validation of numeric inputs is more strictly enforced on load. Previously an out-of-range integer would “wrap” and be ingested as some incorrect value. Numeric-typed columns are now validated, and if validation fails, the row is rejected.

• String dictionary reaching capacity during import now throws an error and stops the load instead of inserting nulls in the dictionary-encoded column.

• Significant performance improvements for load into high-cardinality dictionary-encoded text columns via optimized dictionary hash table resizing.

• Improved load performance on systems with many cores. Default max number of threads to use is capped at 32, instead of 2X the number of cores, which can cause contention on systems with many cores.

• Improved the performance of left join queries with filters by searching for left-hand side filters that can be executed before the join, potentially reducing the cardinality of the join.

• Support date format %m/%d/%y with 2-digit year on data import.

• Improved the performance of common multicolumn sort patterns.

• Chunksize default increased to 2 GB to allow for more records per fragment, particularly when variable-length columns are present (none-encoded strings, arrays, and geospatial types). This allows certain query patterns, such as large joins that might previously span multiple fragments, to run faster.

• Entitlements (introduce simple row level security via SAML attributes).

• Accept session-token when using S3 import, WITH option is s3-session-token.

• Upgrade to calcite 1.25.

• Fixed an issue where SHOW CREATE TABLE would show the wrong table name after a table with shared dictionaries was renamed.

• Resolved an issue where a COPY TO command with a subquery could fail.

OmniSci Rendering

New Features and Improvements

• Improved the quality of density accumulation rendering by incorporating a technique that uses 64-bit atomic operations instead of 32-bit when calculating standard deviation. This allows for a greater range of colors when using statistical measures to color the densities. The 32-bit technique was prone to uncaught overflows that resulted in a much more clamped color range.

• Performance improvement when using a Mercator projection explicitly for marks using the Vega projection property.

• Multi-GPU compositor performance and memory footprint is improved through better pipelining and reduced copy operations.

• New Arrow stock symbol shape can be used in symbol/legacy symbol marks.

• Line and polygon stroke rendering improved by 30-40% by simplifying the math to build the stroke geometry.

• Significant improvements to the quality of point/symbol rendering, achieved by improvements to procedural anti-aliasing technique and to render sample capturing when drawing procedural symbols.

• Polygon geometry imported via the SQLImporter path can now be rendered.

Fixed Issues

• Fixed a bug where decimals are not properly updated in vega scales after an empty render.

• Resolved a small host memory leak in the renderer.

• Fixed a polygon render issue where fully transparent polygons can inadvertently affect the renders of visible neighbors.

• Fixed a crash when attempting to render a line mark layer with opacity explicitly set to 0.

• Fixed a potential race condition when DROP or CREATE is run in between renders or while render is in flight. The race condition could result in a crash when executing the get_result_row_for_pixel endpoint.

• Corrected an issue with multilayer rendering with multiple density accumulation layers where all density layers incorrectly applied the color palette from a single layer.

• Fixed a crash that occured when rendering a line mark in a multi-GPU-configured server/leaf when the number of GPUs required to render the lines jumps from one to more-than-one GPU when rendering consecutive vegas.

• Corrected the stroke rendering of ellipse symbols.

• Corrected possible skew in symbol rendering when using the angle property.

5.4.2 - November 10, 2020

For access to OmniSci release 5.4.2, contact [e-mail].

OmniSci release 5.4.2 includes some new features and improvements and fixes a number of issues.

OmniSciDB

New Features and Improvements

• Improved performance of large group-by queries over dictionary encoded strings when filters are present. The filters are applied to the group by reducing the size of the output.

• Added memory protection for APPROX_COUNT_DISTINCT queries. The configuration parameter bitmap-memory-limit allows you to increase or decrease the maximum amount of memory allocated for APPROX_COUNT_DISTINCT bitmaps per execution kernel (thread or GPU). Previously, this allocation was not capped. The default cap is 8 GB, but can be increased for high-memory systems.

• Added support for PowerBI as an OmniSciDB client.

Fixed Issues

• Resolved an issue where a query with LIMIT 0 in distributed mode could return results.

• Resolved an issue where singleton inserts or updates/deletes on sharded tables in distributed mode could result in truncation of the table.

• Fixed an issue where join queries could return incorrect results with NVIDIA driver 455. OmniSci continues to recommend driver versions 418.39 to 450 for OmniSci release 5.4.x.

• Fixed a crash on unsupported, multi-table self joins.

• Resolved an issue where an entire table could be projected for SELECT * LIMIT n queries, where n is small. OmniSciDB attempts to project only the first n rows, unless deletes without vacuum have occurred.

• Resolved several issues with multistep queries in distributed mode. Stability and performance of multistep queries, multistep queries with subqueries, and multistep subqueries have been improved.

• Fixed an issue with sharded tables in distributed mode where INSERT INTO SELECT queries did not persist changes to disk.

OmniSci Rendering

Fixed Issues

• Resolved an issue where the colors of a symbol render (via a Pointmap in Immerse) can be incorrect if it is immediately preceded by a Heatmap render.

OmniSci Immerse

Fixed Issues

• Fixed issue where users with the CREATE DASHBOARD privilege could not save their dashboards.

5.4.0 - September 4, 2020

OmniSci release 5.4.0 contains several new features and improvements and fixes a number of issues.

OmniSciDB

New Features and Improvements

• Improved performance of the CSV importer by up to 50%. String import, geospatial import via CSV, and importing wide varlen rows are all faster.

• Performance improvements for update and delete queries.

• Improved the performance of filtered group by queries on large cardinality string columns. This is particularly relevant for Immerse-generated cohort queries on dictionary-encoded string columns.

• Upgraded OmniSciDB Arrow distribution to v1.0.0

Fixed Issues

• Can now disable the origin lookup for inbound API requests. On busy systems with slow or throttled networks, DNS lookups can cause bottlenecks as multiple users attempt to access the database. Use the configuration flag log-user-origin.

• Resolved an issue where nested joins within a view could crash.

• Array fields in shapefiles are now imported correctly.

• JDBC driver now returns a valid update count. Currently, OmniSciDB does not report the number of rows updated, so the update count is -1.

• Resolve correctness issues in date/time extract functions.

• Resolved an issue where a Boolean column in an IN expression could crash the server.

• Fixed an issue where listing the roles for the default OmniSciDB user fails. This is resolved only for default users named admin. If your default user is still mapd, you can rename the user to admin by using ALTER USER RENAME TO.

• Resolved an issue where a sort with a limit over sharded or empty data could crash.

• Resolved an issue where some left joins were incorrectly rewritten to inner joins.

• Resolved an issue where a rendering hit test against a sharded table could crash.

  • Change font size, boldness, and contrast across chart titles and labels

  • Customize axis label truncation

  • Modify and add new color palettes

  • Save UI settings as the database-wide default

• Dashboards now have tabs, which can be duplicated and reordered. A Play button makes it easy to cycle through tabs.

• Choropleth, Linemap, and Pointmap charts now support chart-level data export in GeoJSON and CSV formats.

• The min/max axis values for Scatterplot charts can be configured manually.

• The SQL Editor now accepts Vega JSON requests and displays image results in the editor window.

• A lat/long viewer is displayed when hovering over map charts.

• Added the # of Groups functionality to the New Combo chart, providing a consistent experience with other bar charts.

• Added the option to allow zooming on map and combo charts only when the SHIFT key is held down, to prevent accidental zoom actions.

Many of these features can be implemented and customized using feature flags.

Fixed Issues

• Fixed an issue in old Combo charts where charts did not load correctly with updated data.

• Resolved an issue where invalid filters caused dashboards to load incorrectly.

• Fixed an issue in New Combo charts where line marks were displayed as area marks when bar marks were present.

5.3.2 - July 30, 2020

OmniSci release 5.3.2 contains new features and improvements and fixes a number of issues.

OmniSciDB

New Features and Improvements

• Added LEFT JOIN support for accelerated geojoins using the overlaps join.

• Improved performance of projection queries with OFFSET.

• Improved performance of OmniSciDB function calls (e.g. geometric functions) by eliding null checks and eliminating runtime casts.

• Added support for implicit casting during insert into the table as select.

• Improved error messages and logging. In particular for casting errors, union all type mismatch errors, and create table as select / insert into as select logging all.

• During Create table as select, dictionaries between the source and target tables will automatically be shared. This improves the performance of both the CTAS query and of any queries using both tables. Append WITH (USE_SHARED_DICTIONARIES=FALSE) at th end of the CTAS query to disable this option.

• Reduced connection timeout errors by introducing keepalive on API calls that use a client with a timeout (intended to replace manual management of individual service timeouts). keepalive is controllable using the calcite-service-keepalive and leaf-with-keepalive command line options.

Fixed Issues

• Resolved an issue where a case statement in a subquery could crash the server with the error Check failed: generation_ >= 0 (-1 >= 0).

• Fixed an issue where an update on a temporary table could result in no rows being updated after a delete had occurred.

• Overhauled date_trunc and extract runtime, improving performance and resolving correctness issues with dates before January 1, 1970.

• Resolved correctness issues with TIMESTAMPDIFF and DATEADD.

• Resolved an issue where queries could crash the server in a CUDA/Render enabled build running in cpu-only mode. CPU-only builds do not suffer the same problem.

• Resolved an issue where SELECT * LIMIT N (for any N) on a table with deleted rows would pull the entire table into memory.

• Fixed an issue where a validate query preceding a SQL query could cause the error Ran out of slots in the query output buffer during SQL query execution.

• Resolved a crash on group by queries with large output buffers.

OmniSci Immerse

Fixed Issues

• Fixed issue where New Combo chart could not be turned off via feature flag.

• Fixed issue where certain string values were handled incorrectly in Pointmap coloring.

5.3.1 - July 8, 2020

OmniSci release 5.3.1 contains new features and improvements and fixes a number of issues.

OmniSciDB

New Features and Improvements

• GPU memory usage is improved across OmniSciDB and OmniSci Render. Previously, large amounts of reserved GPU memory (res-gpu-mem) were required to prevent out-of-memory errors when rendering large line or polygon datasets. With more buffer sharing between the database and rendering engine, you can reduce the res-gpu-mem value without increasing out-of-memory errors.

• Added a query hint framework, allowing you to control query execution parameters in the query string. You can set CPU execution mode by adding /*+ cpu_mode */ after the SELECT keyword in a SELECT query.

• Performance is significantly improved when sorting on COUNT DISTINCT and APPROX_COUNT_DISTINCT aggregates.

• Performance is improved in query parse, particularly for small-cardinality group-by queries. Additional performance improvements for multicolumn and large-cardinality group-by queries using baseline hash.

• GPU and CPU buffer pool allocation (slab) size are configurable as a runtime parameter, and the default for GPU buffer pool is increased from 2GB to 4GB for more efficient GPU memory usage.

• GPU JIT warmup is added to OmniSciDB at server start. As a result, OmniSciDB verifies the correct CUDA version and generates initial code for the GPU at startup instead of when the first query is executed. First query times on GPU after startup have been reduced. The server does not accept connections during JIT warmup, but a message is printed in the logs before and after warmup completes.

• Access to import/export paths to the server using the COPY command can be restricted. Administrators can restrict access to root paths used in COPY FROM and COPY TO commands. Currently, all paths are allowed by default.

• Added the SQL placeholder CURRENT_USER for accessing the username of the current user in a SQL query.

• Added support for the ALL PRIVILEGES alias when granting object privileges.

Fixed Issues

• Resolved an issue where queries with STDDEV inside a CASE statement could fail with the error message, “Aggregate function STDDEV not supported.”

• Fixed an issue where projecting NULL could crash the server.

• Resolved an issue where TIMESTAMPDIFF could return incorrect results for dates earlier than January 1st, 1970.

• Resolved correctness issues with the EXTRACT function on date, time, and timestamp values. Extract week could return incorrect results, and dates before January 1st, 1970 could also return incorrect results.

• Resolved an issue where getString() on an array returned via JDBC would return an out-of-bounds exception.

• Improved handling of cast and filter operations on high-precision timestamps. Reduced incidence of overflow/underflow errors when casting or filtering between timestamps of different precision.

• Resolved an issue where OmniSci Server could exit without an error code when encountering some errors (for example, too many open files during execution of an import query).

• Resolved an issue where user input was not effectively sanitized.

OmniSci Render

New Features and Improvements

• New extension functions reg_hex_horiz_pixel_bin_packed, reg_hex_vert_pixel_bin_packed, and rect_pixel_bin_packed replace reg_hex_horiz_pixel_bin_x/y, reg_hex_vert_pixel_bin_x/y, and rect_pixel_bin_x/y, respectively. The packed versions return an image coordinate packed into a 32-bit INT, eliminating the need for separate x/y functions and reducing redundancy. Query times are improved up to 2x.

Fixed Issues

• Fixed an intermittent CHECK on a multi-GPU server when rendering a query where the results are distributed to a sparse subset of available GPUs.

• Addressed incorrect renders on multi-GPU servers when the offset-device-by-table-id config flag is enabled. This flag is now enabled by default.

• Fixes an exception safety issue in a multi-GPU server when an out-of-memory exception is thrown in the compositor before resource initialization is complete. This rare scenario would have resulted in a segfault.

• Fixes a CHECK when rendering polygon/multipolygon columns that were imported without an SRID and no encoding defined, usually via CSV when the SRID is not implied.

OmniSci Immerse

New Feature

• Added the ability to build cumulative and percentage distributions in the New Combo chart for non-binned and categorical dimensions.

Fixed Issues

• Fixed issue where binning min/max values were not preserved on table and pie charts.

• Added a feature flag for the SELECT * query snippet in the SQL Editor.

• Fixed bugs in New Combo charts related to top-N, binning, and NULL handling.

• Fixed issue in Table charts where certain measures produced an invalid date filter in Firefox browser.

5.3.0 - June 16, 2020

OmniSci release 5.3.0 contains several new features and improvements and fixes a number of issues.

OmniSciDB

• The render-poly-cache-bytes flag has been removed and must be deleted from configuration files or other start scripts; otherwise, the omnisci_server binary fails to start.

• Clearing the NVIDIA code cache after upgrading OmniSciDB is a best practice. To clear the nvidia code cache, remove the .nv directory in the home directory of the user running OmniSciDB. If you are running in a Docker container, the code cache is automatically cleared when a new container is launched in the default configuration.

• Previously, date_trunc(decade,...) truncated to the start of the “1”s year of the decade. For example, DATE_TRUNC('decade', CAST('1969-12-31 23:59:59' AS TIMESTAMP)) would return `1961-01-01 00:00:00`). Now, DATE_TRUNC(decade,...) returns the start of the “0”s year; for example, `1960-01-01 00:00:00`. This change was made for consistency with other SQL systems. To start decades on the “1”s, use the DATEADD function.

New Features and Improvements

• Array support for the Array type over JDBC.

• Added support for SELECT DISTINCT in UNION ALL. UNION ALL is currently prerelease and must be explicitly enabled in the server configuration file.

• Added a query type return to the sql_execute endpoint, allowing API users to determine if a query altered date or a table or was a read-only query.

• Added support for joins on DECIMAL types.

• Added support for retrieving metadata for a given statement after running SQLPrepare in ODBC. For example, after calling SQLPrepare, the SQLColAttribute will return metadata for columns involved in the query.

• Performance improvements on CUDA GPUs, particularly Volta and Turing. OmniSci now generates PTX code targeted at specific GPU architectures, resulting in increased performance for aggregate workloads. Performance of summation on double precision types has increased by 10x in some instances.

• Increased use of CUDA shared memory, resulting in additional performance increases on aggregate queries in the presence of a group by.

• sql_validate now returns column descriptors for each projected column in the order in which columns appear in the select clause. Previously, column descriptors could be in any order.

Fixed Issues

• Resolved an issue where RESTORE TABLE could be exploited to gain shell access on the running OmniSci server.

• Resolved an issue where incorrect GPU memory requirement estimates for JOIN queries could result in a query that would run on GPU being transferred unnecessarily to CPU.

• Reduced memory fragmentation during select queries, particularly with approx_count_distinct aggregates. OmniSci recommends dropping caches or restarting the system after upgrading to OmniSci 5.3.0 to make more large pages available for the server.

• Resolved an issue where a comparison of geometry types could crash. Most comparisons of geometry types are not yet supported.

• Resolved various crashes when sorting, projecting, or otherwise interacting with geospatial columns. These crashes resulted from an unsupported operation being performed on geospatial data, and now result in error messages.

• Fixed a crash on Boolean comparisons where the Boolean column was declared NOT NULL.

• Resolved an issue where DISTINCT * in a subquery was not respected, resulting in an extra rowid being inserted into the subquery result and skewing the overall distribution in the query. Now, rowid is not present in a SELECT * statement unless explicitly projected.

• Resolved an issue where a syntax error in a SQL statement could cause the aggregator node to crash in a distributed setup.

• Resolved an issue where a multicolumn group-by window function could return incorrect results.

• Resolved an issue where the date_trunc function could return incorrect results for dates before the Unix epoch, January 1st 1970.

• Resolved an issue where dictionary encoded string columns using a shared dictionary would incorrectly have an encoding displayed in SHOW CREATE TABLE;` or `\d`. Now, DDL from a table with columns using a shared dictionary can be copied and pasted directly to create a new, identical table.

• Resolved an issue where multiple filter expressions using OR could cause a crash if the same column was used on the left side of the expression with different casts.

• Added logging for OmniSciDB server shutdowns due to exceeding the maximum number of available open files on the system.

• Resolved an issue where `INSERT INTO` commands sent from the ODBC driver would fail.

• Fixed an issue where a series of nested queries grouping on float columns could give incorrect results.

• Fixed an issue where importing geojson files with embedded dates could truncate the date epoch to 0 or NULL.

• Resolved an issue where ST_Contains queries using the overlaps join framework could crash or return incorrect results.

• Resolved an issue where importing from a parquet file with multiple row groups could return incorrect results.

• Resolved an issue in the ODBC driver where incorrect data could be returned for double precision types.

• Resolved an issue where geospatial joins could return incorrect results.

• Resolved inconsistencies in argument support for date/time functions. Now, all date/time functions should support literal arguments with or without quotes (for example, `date_part(day, …` and `date_part(‘day’, …)`

• Resolved a small memory leak in the OmniSciDB SQL parser.

  • SHOW DATABASES -- Show all databases the user can log in to.

  • SHOW CREATE TABLE -- Show the DDL CREATE TABLE command for a given table.

  • SHOW USER SESSIONS -- Show all persisted sessions on the server (superuser only). Expired sessions are still shown; they are removed from session state on login attempt.

• Added support for the ALTER TABLE DROP COLUMN command.

• Updates and deletes are now supported on temporary tables.

• Added additional UDF command-line options for systems using nondefault Clang++ installation locations.

• Added support for quoted table names in DDL and DML commands. Use quotes if the table name contains special characters or matches a reserved word.

• Added support for window functions in distributed mode.

• JDBC driver updates:

  • Supports the cancel method, requesting that the database cancel the current request. The enable-runtime-query-interrupt flag must be set to TRUE in OmniSciDB configuration.

  • Handles JDBC function escape syntax for the fn keyword.

  • Supports the getMetaData endpoint.

  • Implements setSchema as a null operation (OmniSciDB currently does not support schemas) instead of throwing a "method not implemented" error.
