What's New?

Version 4.8

  • Added support to log the user roles during login, and the ability to use encrypted communication among distributed system components.
  • SpatioTemporal enhancements, including support for the ST_POINT geo constructor and performance improvements for ST_CONTAINS.
  • Performance and memory management improvements including certain high-cardinality GROUP-BY queries, and support for the OPTIMIZE command for sharded tables.
  • Immerse now integrates with JupyterLab. You can send SQL queries to Jupyter from SQL Editor, or access it directly from top level navigation. See Jupyter Integration for setup instructions.
  • Combo chart now supports zooming and panning on large time series measures down to millisecond-level granularity.
  • New Immerse features include the new Dark Mode theme, the ability to duplicate charts within dashboards, and export and import of dashboard metadata.

Version 4.7

  • Added support for Window functions in OmniSciDB. This is an early iteration of an often-requested SQL feature allowing for analytic computations over rolling windows. See the release notes and documentation for details and known limitations.
  • Added support for Visual Data Fusion, the ability to add measures on a combo chart from more than one source table, and also crossfilter across these sources. This is a natural complement to multi-layer geospatial chart.
  • Distributed Rendering support for polygons supporting much larger shape datasets within analytical workflows.
  • Filters on aggregates in Pointmap and Scatter Plot, equivalent to applying a HAVING filter on SQL aggregate queries.
  • INSERT TABLE AS SELECT (ITAS) support in both single-node and Distributed modes, allowing for easier ELT (Extract/Load/Transform) type workflows in OmniSciDB, typically combined with CTAS (CREATE TABLE AS SELECT).
  • Data import status within Immerse for time estimation and import success information.

Version 4.6

  • CTAS (CREATE TABLE AS SELECT) on distributed installations.
  • Import Parquet format data files.
  • Updates on variable length columns.
  • Single Sign-on with SAML for compatibility with Okta and other providers.
  • Extended NULL support for variable length arrays. The full array can now be null, in addition to individual elements.
  • Support for high-precision timestamps, up to nanosecond precision.
  • Improved performance loading String Dictionary from storage.
  • Significantly more scalable rendering from projection (non-aggregate) queries.
  • Immerse Data Manager:
    • Delete, Append, and Truncate (delete all rows from) tables.
    • Auto-detect header rows on import, manually indicate whether the first row is a header row.
  • Immerse:
    • Improved performance for non-aggregated Choropleth/Pointmap/Scatterplot charts.
    • Non-aggregated Choropleth now cross-filters on zoom.

Version 4.5

  • Enterprise trial version is now available.
  • Better memory handling through improved estimation of GPU memory requirements. Automatically run query on CPU if not enough GPU memory is estimated to be available.
  • Better handling of NULL values.
  • DECIMAL/NUMERIC fields can be downcast to different scales and precisions.
  • Dictionary size increased to 2.15 billion entries.
  • Add support for the lasso filter on Linemap chart.
  • Added clarity to formatting options and created a new option to represent billions as B.
  • Default ports changed from 9090-9094 to 6273-6280 to avoid collisions.
  • Renamed key components from MapD to OmniSci. See the Release Notes.

Version 4.4

  • Improved geospatial function support.
  • Support for pct/blend accumulation rendering modes in distributed configurations.
  • Improved error tracking.
  • Support for SAML authentication with Okta.
  • Improved performance on String Dictionary import for multiple String Dictionary-encoded columns.

Version 4.3

  • More robust joins between different types.
  • Better compression on DECIMAL/NUMERIC types.
  • More efficient rendering of lines using the GPU rather than first copying results to the CPU.

Version 4.2

Version 4.1

Version 4.0
