If there are many cores and all of them > are due leadership, then they would have to serially go through the two-way > sync and leadership takeover. > For tens of cores, this could mean 30-40s without leadership before the last > in the list even gets to start the leadership process. If the leadership > process happens in a separate thread, then the cores could all take over in > parallel. -- This message was sent by Atlassian JIRA (v6.2#6252) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
