Summary: [Distributed]Add peer tracker
Key: IOTDB-555
URL: https://issues.apache.org/jira/browse/IOTDB-555
Project: Apache IoTDB
Issue Type: Improvement
Components: Core/Cluster
Reporter: Tan xinyu
At present, even if the follower logs do not keep up with the progress of the
cluster, the leader sends a single log entry which index is lastLogIndex
directly when using appendEntries to the follower, which causes the wrong log
entry to be transmitted. In fact, as long as the leader maintains the status of
the followers, he can know which log should be transmitted, which greatly
reduces the probability of transmitting wrong log entries.
