Changelog

General Changes

DateVersionSourceCategoryTypeDescription
2026-09-2026.0.9759GeneralConnectionAdded
  • Added the FirewallAutoDetect connection property. When set to False (default), automatic runtime/proxy detection is disabled. Users can configure firewall-related properties manually. When set to True, the driver detects proxy settings automatically. Detected settings take precedence over all manually configured firewall-related properties. If no proxy is detected, manual firewall settings are not used as a fallback.
    • Automatic detection uses JVM proxy settings and honors http.nonProxyHosts. Setting FirewallAutoDetect to False does not disable the JDK's own SOCKS proxy behavior. socksProxyHost settings can still affect socket connections independently of this property.
2026-08-2626.0.9734Amazon S3Data ModelAdded
  • Added the ETagObjectSource input parameter to the CopyObject stored procedure. The operation succeeds only when the specified ETag matches the current ETag of the source object.

  • Legacy connectors have been simplified to look more like Tableau JDBC dialogs. Legacy connectors target older Tableau versions which do not support rich connection dialogs like the modern connectors do. Most connectors cannot fit within these limitations.
2022-05-0522.0.8160Amazon S3Added
  • Added the BucketsCompliance and ObjectsCompliance tables.
2022-03-1621.0.8110Amazon S3Added

  • Added the new sys_primarykeys system table.
2021-07-2321.0.7874GeneralChanged
  • Updated the Literal Function Names for relative date/datetime functions. Previously, relative date/datetime functions resolved to a different value when used in the projection as opposed to the predicate. For example: SELECT LAST_MONTH() AS lm, Col FROM Table WHERE Col > LAST_MONTH(). Formerly, the two LAST_MONTH() methods would resolve to different datetimes. Now, they will match.
  • As a replacement for the previous behavior, the relative date/datetime functions in the criteria may have an 'L' appended to them. For example: WHERE col > L_LAST_MONTH(). This will continue to resolve to the same values that were previously calculated in the criteria. Note that the "L_" prefix will only work in the predicate - it not available for the projection.
2021-07-2321.0.7874Amazon S3Added
  • Added multi-thread multi-part upload support for the UploadObject procedure. Set the value of the ChunkSize to -1 if you want to disable the multi part logic.

  • Removed the SimpleUploadLimit connection property. We will perform multi-part upload by default in the UploadObject procedure. The number of parallel calls can be controlled by the MaxThreads connection property.
2021-05-1721.0.7807Amazon S3Added
  • Added support for Single Sign On (SSO) connection with PingFederate as the Identity Provider (IdP).
2021-04-2321.0.7783GeneralChanged

  • Reduced the length to 255 for varchar primary key and foreign key columns.
2021-04-1621.0.7776GeneralChanged

2021-04-1621.0.7776GeneralChanged
  • Updated index naming convention to avoid duplicates.
2021-04-1621.0.7776TableauChanged
