[jira] [Commented] (KUDU-1913) Tablet server runs out of threads
when creating lots of tablets
[ https://issues.apache.org/jira/browse/KUDU-1913?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16013264#comment-16013264 ]
Todd Lipcon commented on KUDU-1913:
-----------------------------------
6311acb2faf4f78964fe95cb07ab9331bc2657f7 made some progress on this. Now, idle tablets with no ongoing writes will not occupy an AppendThread.
[~adar] is separately working on a patch to reduce the raft threads.
