Rocksdb will do compaction. I am not sure how to make it works with raft log.

Do you know if they support compaction?
BTW, MySQL has a pluggable storage but rocksdb seems not.

> [~szetszwo] Hi, this is just a discussion.
> Currently, when ratis commit log, ozone will write data to Rocksdb. In my
> thinking, raft write raft log on disk, and rocksdb also write wal log on
> disk, there are two log need to be wrote. If rocksdb can avoid writting wal
> log, and use raft log directly, it can improve performance, but we need to

> I just throw this idea, because I do not know how to change the code of
> Rocksdb. Baidu company has changed mysql to use raft log, and avoid writting
> binlog.
