Subject [jira] Commented: (LUCENE-2960) Allow (or bring back) the ability to setRAMBufferSizeMB on an open IndexWriter
Date Thu, 10 Mar 2011 20:44:59 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-2960?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13005323#comment-13005323

Michael McCandless commented on LUCENE-2960:
--------------------------------------------

bq. Really this is our mistake, we shouldn't have committed IWC and left TestIndexWriter.testChangingRamBufferSize
or whatever using the deprecated setter without hashing this out further: because this test
would fail if it tried to use IWC.

I agree.  Really we should not commit API changes w/o also cutting over all but a few (so
we still test the deprecated path) usages of the deprecated API to the new one (and addressing
whatever issues that uncovers).

> In 3.1 the ability to setRAMBufferSizeMB is deprecated, and removed in trunk. It would
be great to be able to control that on a live IndexWriter. Other possible two methods that
would be great to bring back are setTermIndexInterval and setReaderTermsIndexDivisor. Most
of the other setters can actually be set on the MergePolicy itself, so no need for setters
for those (I think).
