ASF GitHub Bot commented on KAFKA-7568:
---------------------------------------

hachikuji opened a new pull request #5855: KAFKA-7568; Return leader epoch in ListOffsets response
URL: https://github.com/apache/kafka/pull/5855
 
 
   As part of KIP-320, the ListOffsets API should return the leader epoch of any fetched offset. We either get this epoch from the log itself for a timestamp query or from the epoch cache if we are searching the earliest or latest offset in the log. When handling queries for the latest offset, we have elected to choose the current leader epoch, which is consistent with other handling (e.g. OffsetsForTimes).

> This is part of KIP-320. The changes to the API have already been made, but currently we return unknown epoch. We need to update the logic to search for the epoch corresponding to a fetched offset in the leader epoch cache.
