Mark Miller commented on SOLR-6930:
-----------------------------------
bq. I'm not a big fan of estimation and pre-emptive termination based on
estimates.
You would be if you operated a SolrCloud cluster with various clients doing
different things. You need to be able to lock things down to prevent OOM's
(which dictate restarts). For someone like you, you can turn off the circuit
breakers or not enable them, but not doubt they are of great value for anyone
running SolrCloud as a service (a common use case).

> 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.
