Justin Sweeney commented on SOLR-16974: --------------------------------------- Curious on thoughts for how per-core vs per-node circuit breakers should interact. Here is one potential option: I could envision it working where per-node are used as defaults and per-core are more specific overrides. In that case, we would want to only check the global circuit breakers if there are no per-core circuit breakers enabled of a given type. For example, in an environment with Collection A, Collection B, and Collection C, if per-node CPU circuit was configured for 80%, but Collection A had a per-core circuit configured for 90%, we should not trip requests to Collection A when CPU is at 85%, but we would trip requests to Collections B and C. I'd imagine typical usage would just be configuring global circuit breakers per node, but the per-core would be more advance usage in multi-collection environments.
