runzhiwang updated RATIS-1327:
------------------------------
Description:
[~szetszwo] Hi, this is just a discussion.
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
change the code of rocksdb.
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.
> Discussion about merging the wal log of RocksDB and raft log
