---------------------------------------
hachikuji commented on pull request #6943: KAFKA-8542; Cache transaction first
offset metadata on follower
URL: https://github.com/apache/kafka/pull/6943
Followers should cache the log offset metadata for the start offset of each
transaction in order to be able to compute the last stable offset without an
offset index lookup. This helps with follower fetching in KIP-392.
