To address this problem, we have introduced a new feature called synchronous replication. As the mechanism is a bit different so we use a separated section to describe it. Please see <>. +NOTE: At present, there is compatibility problem if Replication and WAL Compression are used together. If you need to use Replication, it is recommended to set the `hbase.regionserver.wal.enablecompression` property to `false`.
