-----------------------------------

[~hachikuji], no problem. BTW, the queries are old and I have created a PR for 
this change. You can review whenever you get a chance.

> Raft leader should flush accumulated writes after a min size is reached

> In KAFKA-10601, we implemented linger semantics similar to the producer to 
> let the leader accumulate a batch of writes before fsyncing them to disk. 
> Currently the fsync is only based on the linger time, but it would be helpful 
> to make it size-based as well. In other words, if we accumulate a 
> configurable N bytes, then we should not wait for linger expiration and 
> should just fsync immediately.
