IndexWriter does not properly account for the RAM consumed by pending deletes
-----------------------------------------------------------------------------
Key: LUCENE-1717
URL: https://issues.apache.org/jira/browse/LUCENE-1717
Project: Lucene - Java
Issue Type: Bug
Affects Versions: 2.4.1, 2.4
Reporter: Michael McCandless
Fix For: 2.9
IndexWriter, with autoCommit false, is able to carry buffered deletes for quite
some time before materializing them to docIDs (thus freeing up RAM used).
It's only on triggering a merge (or, commit/close) that the deletes are
materialized and the RAM is freed.
I expect this in practice is a smallish amount of RAM, but we should still fix
it.
I don't have a patch yet so if someone wants to grab this, feel free!!
