vinothchandar commented on pull request #7961: [KAFKA-9431] Expose API in
KafkaStreams to fetch all local offset lags
URL: https://github.com/apache/kafka/pull/7961
- Adds KafkaStreams#allLocalOffsetLags(), which returns lag information of
all active/standby tasks local to a streams instance
- LagInfo class encapsulates the current position in the changelog,
endoffset in the changelog and their difference as lag
- Lag information is a mere estimate; it can over-estimate (source topic
optimization), or under-estimate.
- Each call to allLocalOffsetLags() generates a metadata call to Kafka
brokers, so caution advised
- Unit and Integration tests added.
### Committer Checklist (excluded from commit message)
