Ishan Chattopadhyaya commented on SOLR-15715:
---------------------------------------------
I'd like to point out here that this feature is a donation from FullStory,
where [~hiteshkhamesra] implemented this solution that has already brought
immense benefits on large Solr clusters. As part of this JIRA, we plan to
upstream that functionality so that broader Solr community can benefit. While
we've seen substantial reduction of memory usage on data hosting nodes in
production at FullStory's internal workloads, I shall publish benchmarks for
this feature on publicly available datasets soon.
> Dedicated query aggregator nodes in the solr cluster.

> 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
> Priority: Major
>
> 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
