> There are several JIRAs (I'll link in a second) about trying to be more efficient about processing overseer messages as the overseer can become a bottleneck, especially with very large numbers of replicas in a cluster. One of the approaches mentioned near the end of SOLR-5872 (15-Mar) was to "read large no:of items say 10000. put them into in memory buckets and feed them into overseer....".
> This JIRA is to break out that part of the discussion as it might be an easy win whereas "eliminating the Overseer queue" would be quite an undertaking.
