----------------------------------------
{quote}I think there's no use-case for that – users should only reference
collections (any node) or a core on a node where it's known to exist (on that
node!)

What about folks accessing Solr through a load-balancer [~dsmiley]?
Personally I often make core-specific "/luke", "/segments", etc. requests when
debugging. It seems like this would make those APIs unusable for anyone going
through a LB (!)

> If a SolrCloud node receives a request with a local core name (not a
> collection name), it will be handled by the local core. But it even works
> with a remote core -- it'll be forwarded to the node that has a core by that
> name. I think there's no use-case for that -- users should only reference
> collections (any node) or a core on a node where it's known to exist (on that
> node!) since it's a core not a cluster concept. This got my attention
> because the functionality requires iterating all collections. This would
> happen for any request when a collection/core is not known to the node (and
> may not exist at all). I shall remove this in Solr 10.
> There is exactly one test for this functionality --
> {{org.apache.solr.cloud.AbstractBasicDistributedZk2TestBase#addAndQueryDocs}}
