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 {{% gh 25418 %}}.
