-------------------------------
Summary: [Distributed] Add the ability to resolve log
inconsistencies for AppendEntries request
Key: IOTDB-554
URL: https://issues.apache.org/jira/browse/IOTDB-554
Project: Apache IoTDB
Issue Type: Improvement
Components: Core/Cluster
Reporter: Tan xinyu
Currently the leader use heartbeat requests to periodically resolve log
conflicts, while AppendEntries is only used to synchronize the latest log
entry, even if the logs do not match. If there is an inconsistency in the log
between nodes, the leader can only wait for a periodic heartbeat to try to
solve it, but cannot solve it in a short time, which eventually leads to poor
read performance. In fact, the leader should try to resolve the conflict as
soon as they encounter a conflict after sending an AppendEntries request.
