everything.{quote}
I agree that it is a bit "kludgey". However I do not believe all roles need to
register some data with CoreContainer. I shall try to make it cleaner
> Dedicated query aggregator nodes in the solr cluster.

> We have a large collection with 1000s of shards in the solr cluster. We have
> observed that distributed solr query takes many resources(thread, memory,
> etc.) on the solr data node(node which contains indexes). Thus we need
> dedicated query nodes to execute distributed queries on large solr
> collection. That would reduce the memory/cpu pressure from solr data nodes.
> Elastis search has similar functionality
