Hi Erick, I agree but in a huge cluster the retries keeps on happening, cant we have this feature implemented in client. i was referring to this jira https://issues.apache.org/jira/browse/SOLR-10479 We have seen that some malicious queries come to system which takes significant time and these queries propagating to other solr servers choke the entire cluster.
