[jira] [Comment Edited] (HBASE-26220) Use P2P communicate between
region servers to sync the list for bootstrap node
[ https://issues.apache.org/jira/browse/HBASE-26220?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17419301#comment-17419301 ]

-------------------------------------------------------------
I think this is a very important improvements.
In the current implementation, every region server needs to watch all the region servers in the cluster, through a zk watcher, which put big pressure on zookeeper for a large cluster.
We'd better land this before cutting 2.5.0, but maybe we need a backport issue as the implementation will be different since there is no AsyncClusterConnection for branch-2.

> For returning bootstrap nodes to client, we do not need to always track exactly the current live region server. But now, we just set a watcher on zookeeper to watch all the live region servers, on every region server, for large cluster, it will be a big pressure for zookeeper.
> So here I think, we could let region servers to communicate with each other to sync the available bootstrap node, like a P2P network.
> Will put a simple design doc soon.
