Houston Putman created SOLR-17893:
-------------------------------------
Summary: Solr RemoteProxy does not scale when running at a high QPS
Key: SOLR-17893
URL: https://issues.apache.org/jira/browse/SOLR-17893
Project: Solr
Issue Type: Improvement
Components: SolrCloud
Reporter: Houston Putman
When running at a high QPS, the Remote Proxy (previously Remote Query) code in
HttpSolrCall can slow down drastically. This is because two ZK calls are made
on every request in a synchronous block, because caching is not used (And the
caching logic in ZkStateReader has a bug). At QPS > 1k, these synchronized ZK
calls become very burdensome if not running in an embedded mode.
