Bug fixes in this release

  • This release fixes a bug causing incorrect recording of lineage for streaming tables.

  • With this release, streaming flows are started after all dependencies have completed processing. Previously, a streaming flow might begin processing before its dependencies are complete, leading to data loss in some cases.

  • This release includes changes to fix a bug causing maintenance jobs to fail for some pipelines. In continuous pipelines, for an APPLY CHANGES INTO target without z-order columns specified, the OPTIMIZE operation is skipped when the maintenance tasks are performed, and auto-compact is enabled.
