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).
