Description

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 here
