Simon Willnauer resolved LUCENE-9304. ------------------------------------- Fix Version/s: 8.6 master (9.0) Lucene Fields: New,Patch Available (was: New) Assignee: Simon Willnauer Resolution: Fixed > Clean up DWPTPool > ------------------ > > Key: LUCENE-9304 > URL: https://issues.apache.org/jira/browse/LUCENE-9304 > Project: Lucene - Core > Issue Type: Improvement > Affects Versions: master (9.0), 8.6 > Reporter: Simon Willnauer > Assignee: Simon Willnauer > Priority: Major > Fix For: master (9.0), 8.6 > > Time Spent: 9h 10m > Remaining Estimate: 0h > > DWPTPool currently uses an indirection called ThreadState to hold DWPT > instances. This class holds several information that belongs in other places, > inherits from ReentrantLock and has a mutable nature. Instead we could pool > the DWPT directly and remove other indirections inside DWPTFlushControl if > we move some of the ThreadState properties to DWPT directly. The threadpool > also has a problem that is grows it's ThreadStates to the number of > concurrently indexing threads but never shrinks it if they are reduced. With > pooling DWPT directly this limitation could be removed. > In summary, this component has seen quite some refactoring and requires some > cleanups and docs changes in order to stay the test of time. -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@lucene.apache.org For additional commands, e-mail: issues-h...@lucene.apache.org
