Subject [jira] [Commented] (LUCENE-8081) Allow IndexWriter to opt out of flushing on indexing threads
Date Wed, 06 Dec 2017 17:52:00 GMT

Michael McCandless commented on LUCENE-8081:
--------------------------------------------

+1

Maybe expand the javadoc a bit to state that this means the thread calling {{refresh}} will
be the only thread writing new segments to disk, unless flushing falls behind?

> Today indexing / updating threads always help out flushing. Experts might want indexing
threads to only help flushing if flushes are falling behind. Maybe we can allow an expert
flag in IWC to opt out of this behavior.
