Mark Miller commented on SOLR-6930:
-----------------------------------
Does SOLR-5986 actually use fieldcache sizing estimates to prevent OOM's or
asking for too many rows back? I thought it was more about timing out bad
queries...overlap, but large differences.
> Provide "Circuit Breakers" For Expensive Solr Queries

> ES currently allows operators to configure "circuit breakers" to preemptively
> fail queries that are estimated too large rather than allowing an OOM
> Exception to happen. We might be able to do the same thing.
