> Project: Solr
> Issue Type: New Feature
> Components: Circuit Breakers

> Currently Circuit Breakers are configured per core in solrconfig.xml.
> However, cores/collections do not live in isolation, and it could be that a
> cluster administrator would like to enforce circuit breakers for the entire
> cluster.
> I'm not clear as to whether we need both cluster level and a core level
> pluggability. And would core-level breakers add to any cluster-level ones or
> override them for that core?
> A potential design is to add this as a new plugin in solr.xml, and have them
> added in a new static context of CircuitBreakerRegistry. Then the isTripped
> logic would consult both the per-core list and the static/global list of
> breakers.
