David Smiley commented on SOLR-14423:
-------------------------------------
Following up to those here; I'm discussing with others in SOLR-17630 about
deprecating CoreContainer.getSolrClientCache in lieu of a node CloudSolrClient
and node Http2SolrClient (that can use any URL to talk to whoever) for general
inter-node use. SCC then becomes something only needed by the streaming
expressions framework, so would likely go back there. If you have thoughts,
please raise them there.
> static caches in StreamHandler ought to move to CoreContainer lifecycle

> StreamHandler (at "/stream") has several statically declared caches. I think
> this is problematic, such as in testing wherein multiple nodes could be in
> the same JVM. One of them is more serious -- SolrClientCache which is
> closed/cleared via a SolrCore close hook. That's bad for performance but
> also dangerous since another core might want to use one of these clients!
