Yongzao Dan created IOTDB-4685:
----------------------------------
Summary: Consensus heartbeat statistics
Key: IOTDB-4685
URL: https://issues.apache.org/jira/browse/IOTDB-4685
Project: Apache IoTDB
Issue Type: Improvement
Reporter: Yongzao Dan
Assignee: Yongzao Dan
Fix For: 0.14.0
Currently, all heartbeat samples are cached above the consensus layer of
ConfigNode, which connotes that all load statistics will be discarded as long
as the leader of ConfigNode is switched. Obviously, the following kinds of
loadStatistics are worth to consensus:
* The status of cluster Nodes and RegionGroups
* The leader of RegionGroup
* The loadScore of cluster Nodes and RegionGroups(will be implemented in the
future)
Therefore, I refactor the framework of cluster heartbeat related threads, and
you can find the detailed desgin in the [LoadBalancing
Framework|https://apache-iotdb.feishu.cn/docx/doxcnZ2tquzJKINQWi9nnYECPCb] doc.
