Subject [jira] [Commented] (PHOENIX-3970) Ensure that automatic partial index rebuilds are served from the index handler pool
Date Thu, 22 Jun 2017 23:08:00 GMT

    [ https://issues.apache.org/jira/browse/PHOENIX-3970?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16060164#comment-16060164

Lars Hofhansl commented on PHOENIX-3970:
----------------------------------------

Yes, that's possible. I suppose scan and index write on different pools _is_ better from that
angle.
But it does not solve the fundamental problem of hanging handler threads.

OK... Should I close this one then?

The right(tm) solution is to rebuild indexes asynchronously (either by returning immediately
from the scans after scheduling the work, or my using the offline index build tools, which
since 2.10 can also do partial rebuilds).
