Rittika Adhikari updated KAFKA-13803:
-------------------------------------
Description:
Currently, AbstractFetcherThread has a series of protected APIs which control
access to the Leader. ReplicaFetcherThread and ReplicaAlterLogDirsThread
respectively override these protected APIs and handle access to the Leader in a
remote broker leader and a local leader context.
We propose to move these protected APIs to a LeaderEndPoint interface, which
will serve all fetches from the Leader. We will implement a
RemoteLeaderEndPoint and a LocalLeaderEndPoint accordingly. This change will
greatly simplify our existing follower fetch code.
