Jan Høydahl commented on SOLR-16974:
------------------------------------
I have continued on the PR to parse ENV/SysProp. Ideally I'd like to have the
bin/solr script capture all env.vars starting with {{SOLR_}} and inject them to
Solr, and then Solr can convert them to sysprops, by lowercasing and replacing
"_" with ".". I'm not very happy with having to add six more env -> prop
clauses to both linux and windows start scripts. [~epugh] you have some PR
in-flight moving more logic over to Java, have you done anything there related
to converting ENV --> sysprop?

> Key: SOLR-16974
> URL: https://issues.apache.org/jira/browse/SOLR-16974
> Project: Solr
> Issue Type: New Feature
> Security Level: Public(Default Security Level. Issues are Public)
> Components: Circuit Breakers
> Reporter: Jan Høydahl
> Assignee: Jan Høydahl
> Priority: Major
> Time Spent: 0.5h
> Remaining Estimate: 0h
>
> 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.
