Mike Drob created LUCENE-9504:
---------------------------------
Summary: DocumentsWriterDeleteQueue.forceApplyGlobalSlice has
needless locking
Key: LUCENE-9504
URL: https://issues.apache.org/jira/browse/LUCENE-9504
Project: Lucene - Core
Issue Type: Improvement
Components: core/index
Reporter: Mike Drob
{{DocumentsWriterDeleteQueue.forceApplyGlobalSlice}} is only called from
{{getBufferedUpdateTermsSize}} so we end up doing double the locking. It's not
a huge problem because re-entrant locks are cheap, but we can probably unwrap
the methods a little bit here.
This may impact HotSpot inlining, I haven't tried measuring that yet. If that
is a concern, please let me know.
