---------------------------------------
Summary: Raft client should push all committed data to listeners
Key: KAFKA-10632
URL: https://issues.apache.org/jira/browse/KAFKA-10632
Project: Kafka
Issue Type: Sub-task
Reporter: Jason Gustafson
Assignee: Jason Gustafson
We would like to move to a push model for sending committed data to the state
machine. This simplifies the state machine a bit since it does not need to
track its own position and poll for new data. It also allows the raft layer to
ensure that all committed data up to the state of a leader epoch has been sent
before allowing the state machine to begin sending writes. Finally, it allows
us to take advantage of optimizations. For example, we can save the need to
re-read writes that have been sent to the leader; instead, we can retain the
data in memory and push it to the state machine after it becomes committed.
