Matthias J. Sax updated KAFKA-20744:
------------------------------------
Description:
KIP-1017 ([KIP-1071: Streams Rebalance
Protocol|https://cwiki.apache.org/confluence/spaces/KAFKA/pages/311627992/KIP-1071+Streams+Rebalance+Protocol])
proposed to deprecate and remove the Kafka Streams config
`rack.aware.assignment.tags`. This is correct by itself, but incomplete,
because we need this config broker side.
So far, it was no a problem because rack-aware standby task assignment was not
implemented yet, and while KIP-1071 is already GA with 4.2.0 release, it's not
feature complete yet.
The KIP was updated and corrected now. This ticket is about closing this broker
side gap, and add `rack.aware.assignment.tags` as broker and group-level config.
After this ticket is resolved, assignors can use the rack information to assign
standby tasks in a rack-aware manner. This will be follow up work not covered
by this ticket.
