What’s New With KSQL

Hojjat Jafarpour announces Kafka’s KSQL version 0.3:

Additionally, we have taken the first steps to provide metrics and observability in KSQL. This greatly enhances the operability of KSQL, like in cases where you’re monitoring KSQL capacity or when diagnosing issues. You can now see different metrics for streams, tables, and queries for every KSQL server instance.

For streams and tables, we now have DESCRIBE EXTENDED <stream/table name> statement to show statistics, such as number of messages processed per second, total messages, the time when the last message was received, as well as corresponding failure metrics.

Looks like they’re building it out a piece at a time.
