Mike Drob commented on SOLR-6930:
---------------------------------
bq. I'm not a big fan of estimation and pre-emptive termination based on
estimates.
I agree with the implied position about this being hard to get right. It's very
easy to set limits that are too high so as to be useless or too low as to be
suffocating.

> 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.
