---------------------------------------------
{quote}Regarding the "need is high" for scaling up these query aggregation
nodes, I think it is dependent on the workload and I'm not at liberty to
disclose the exact details of FullStory's production workload.

Having said that, I don't expect that anyone except a tiny minority of users
would find this feature helpful. And, as you mentioned, even for those who find
this useful, it might be necessary to weigh the tradeoffs that are involved
(having additional nodes on top of the data nodes vs. whatever benefits can be
had). This is going to be an opt-in feature. In this JIRA, I don't think we can
address all such real world scenarios in order to be able to provide definitive
guidance whether this will be useful for a particular scenario or not.

> 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
