Subject Re: need help in understating solr cloud stats data

Hi,

Oh, I just saw Greg's email on dev@ about this.
IMHO aggregating in the search engine is not the way to do.  Leave that to
external tools, which are likely to be more flexible when it comes to this.
 For example, our SPM for Solr can do all kinds of aggregations and
filtering by a number of Solr and SolrCloud-specific dimensions already,
without Solr having to do any sort of aggregation that it thinks Ops people
will really want.
