Simon Willnauer created LUCENE-8269: ---------------------------------------
Summary: Detach downstream classes from IndexWriter Key: LUCENE-8269 URL: https://issues.apache.org/jira/browse/LUCENE-8269 Project: Lucene - Core Issue Type: Improvement Affects Versions: 7.4, master (8.0) Reporter: Simon Willnauer Fix For: 7.4, master (8.0) IndexWriter today is shared with many classes like BufferedUpdateStream, DocumentsWriter and DocumentsWriterPerThread. Some of them even acquire locks on the writer instance or assert that the current thread doesn't hold a lock. This makes it very difficult to have a manageable threading model. This change separates out the IndexWriter from those classes and makes them all independent of IW. IW now implements a new interface for DocumentsWriter to communicate on failed or successful flushes and tragic events. This allows IW to make it's critical methods private and execute all lock critical actions on it's private queue that ensures that the IW lock is not held. Follow-up changes will try to detach more code like publishing flushed segments to ensure we never call back into IW in an uncontrolled way. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
