Subject [jira] Commented: (LUCENE-2960) Allow (or bring back) the ability to setRAMBufferSizeMB on an open IndexWriter
Date Fri, 11 Mar 2011 14:14:59 GMT

Yonik Seeley commented on LUCENE-2960:
--------------------------------------

bq. InfoStream, for example, should remain live

Agree - it's logging.

bq. But take MergedSegmentWarmer (used to be live but is now unchangeable). This is a setting
that obviously can easily remain live; there's no technical reason for it not to be.

Anyone's implementation can be live (i.e. the impl could change it's behavior over time for
whatever reason).

> 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).
