Describe the question

HostManager.select() will call workerGroupMapper.queryAllWorkerGroup() or workerGroupMapper.queryWorkerGroupByName(workerGroupName) from database, and call registryCenter.getRegisterOperator().get(workerGroupPath + "/" + node) from zookeeper.

They will cause more queries, even if these queries rarely change.

What are the current deficiencies and the benefits of improvement

  • Optimize and reduce worker group queries of database and zookeeper

Which version of DolphinScheduler:
-[1.3.5]
-[dev]
