             Summary: Reduce the serialization size for the Datanode consensus 
layer
                 Key: IOTDB-3385
                 URL: https://issues.apache.org/jira/browse/IOTDB-3385
             Project: Apache IoTDB
          Issue Type: Improvement

Datanode currently uses FI to pass changes to the consensus layer, but its 
serialization method contains many unnecessary parts, such as replication group 
endpoints and so on, which makes it write much more data than WAL or MLOG, 
affecting performance. We need to think about reducing its size
