Subject [jira] [Commented] (SOLR-2567) Solr should default to TieredMergePolicy
Date Wed, 01 Jun 2011 20:54:47 GMT


Yonik Seeley commented on SOLR-2567:

bq. the patch currently adjusts the default based on luceneMatchVersion, but this is confusing
if we release 3.2 that "disagrees" with lucene's actual 3.2 defaults.

I don't think all of Solr's defaults need to match Lucene's defaults in general - we can take
it on a case-by-case basis.  In this case, a TieredMergePolicy default certainly does make
sense.  I'm not even sure it needed to be linked to luceneMatchVersion... it's a rare solr
user that would depend on the specifics of merging or docid behavioral changes.
