Materialize v0.89

v0.89

Sources and sinks

• Improve source and sink statistics reporting to no longer reset on restarts, and include the following new metrics in mz_internal.mz_source_statistics:

  Metric	Description
  snapshot_records_known	The size of the source’s snapshot.
  snapshot_records_staged	The amount of the source’s snapshot Materialize has read.
  snapshot_committed	Whether the initial snapshot for a source has been committed.
  offset_known	The offset of the most recent data in the source’s upstream service that Materialize knows about.
  offset_committed	The offset of the source’s upstream service Materialize has fully committed.

  These changes will be available in the Materialize console soon, so you can more easily monitor snapshot and ingestion progress for your sources.

SQL

• Remove the mz_activity_log system catalog view. These view was superseeded by mz_recent_activity_log, which contains a log of the SQL statements that have been issued to Materialize in the past 3 days.

• Add mz_internal.mz_compute_operator_hydration_statuses to the system catalog. This table describes the dataflow operator hydration status of compute objects (indexes or materialized views).

Bug fixes and other improvements

• Temporarily disallow ALTER CONNECTION commands on sources using the UPSERT envelope (#25418).
