[jira] [Created] (IOTDB-1163) Optimize the insertion speed of insertRecords interface in Session

Houliang Qi created IOTDB-1163:
----------------------------------

             Summary: Optimize the insertion speed of insertRecords interface in Session
                 Key: IOTDB-1163
                 URL: https://issues.apache.org/jira/browse/IOTDB-1163
             Project: Apache IoTDB
          Issue Type: Improvement
            Reporter: Houliang Qi
             Fix For: 0.12.0


At present, the insertRecords interface generates an InsertRowPlan for each record of data. In this way, a raft log will be generated in the cluster version. Because every raft log will be locked, it will bring a lot of overhead.

At the same time, if some records belong to the same raft replication group, they can be sent to other nodes of this raft group as a raft log, which will reduce the transmission of RPC.

 

For example, 10 records belong to the same raft replication group. If the 10 records are regarded as a raft log, one node needs one RPC. If each log is regarded as a raft log, it needs 10 RPCs.
