Shalin Shekhar Mangar commented on SOLR-617:
--------------------------------------------
This is looking great. Thanks!
We need a few tests for this. With the recent changes in Lucene trunk, we can
get rid of the wrapper over IndexCommit. We need to support maxCommitAge too so
that users who do a lot commits can reliably replicate without storing too many
generations.

> Lucene API provides means to configure deletion policy. Solr should be able
> to expose it through configuration in solrconfig.xml. Moreover the new
> replication (SOLR-561) strategy is going to rely on this .
> I propose the configuration go into the <mainIndex> section
> sample configuration
> {code:xml|title=solrconfig.xml}
> <mainIndex>
> <!-- configure deletion policy here-->
> <deletionPolicy>
> <!-- Store only the commits with optimize.Non optimized commits will
> get deleted by lucene when
> the last IndexWriter/IndexReader using this commit point is
> closed -->
> <keepOptimizedOnly>true</keepOptimizedOnly>
> <!--Maximum no: of commit points stored . Older ones will be cleaned
> when they go out of scope-->
> <maxCommitsToKeep></maxCommitsToKeep>
> <!-- max age of a stored commit-->
> <maxCommitAge></maxCommitAge>
> </deletionPolicy>

> </mainIndex>
