Lianet Magrans commented on KAFKA-18729: ---------------------------------------- [~m1a2st] more context: Initial PR discussion here [https://github.com/apache/kafka/pull/18777#discussion_r1941488787] Good to tackle this one with https://issues.apache.org/jira/browse/KAFKA-18117 in mind, just to be on the same page about moving towards topicIds (instead of topicNames) whenever possible. I'll start working on 18117 soon (right after wrapping up 4.0) > Improve consumer check for assigned topics from regex > ----------------------------------------------------- > > Key: KAFKA-18729 > URL: https://issues.apache.org/jira/browse/KAFKA-18729 > Project: Kafka > Issue Type: Improvement > Components: consumer > Reporter: Lianet Magrans > Assignee: 黃竣陽 > Priority: Major > Fix For: 4.1.0 > > > When using subscriptions to broker-side regex RE2J, the consumer checks if a > topic received in metadata is assigned in order to keep its info. At the > moment, the consumer has no other way but to check the topic against the list > of assigned topicPartitions (which is all that's available). > We should consider improving the check to do it at the topic level, not > topicPartition level . We would need to keep the set of assigned topics from > RE2J regex in the subscription state, updated as assignments as reconciled > and partitions are add/removed. Then we could rely on this topic set for the > check (not all the assigned topicPartitions set) -- This message was sent by Atlassian Jira (v8.20.10#820010)
