Hi Chetan, I agree index time aggregation will be probably faster but I'd like the Solr index to be able to do both so that it's on par with the Lucene index features. On a side note the mentioned commit would only work pre-OAK-2119 so the next step will be (I'm currently working on it) to properly move to implement the AdvanceQueryIndex.
On a related note it'd be probably good to add some benchmarks on query time / index time aggregation performances for Lucene (and for Solr once available) to have a proper evidence of what we expect.
