--------------------------------------

             Summary: Dedicated query aggregator nodes in the solr cluster. 
                 Key: SOLR-15715
                 URL: https://issues.apache.org/jira/browse/SOLR-15715
             Project: Solr
          Issue Type: New Feature
      Security Level: Public (Default Security Level. Issues are Public)
          Components: SearchComponents - other
    Affects Versions: 8.10.1
            Reporter: Hitesh Khamesra


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
