----------------------------------
Summary: Syncleader optimization
Key: IOTDB-1502
URL: https://issues.apache.org/jira/browse/IOTDB-1502
Project: Apache IoTDB
Issue Type: Improvement
Components: Cluster
Reporter: Houliang Qi
At present, there are many operations of *syncLeader*: they are roughly divided
into two categories:
1. Need to synchronize metadata such as storage group;
2. Need to synchronize data;
At present, for *syncLeader* operations, the local raft commit index should be
consistent with the leader commit index. In fact, it is unnecessary to
synchronize metadata. Because this raft log may be a data operation.
Due to the storage group has the concept of version, the metadata
synchronization operation can be synchronized by the storage group version[1],
avoid unnecessary data synchronization and save time.
