Mark Miller commented on SOLR-6379:
-----------------------------------
bq. If that is addressed , I don't really have any objection to the solution
itself.
You do know the performance cost of that call don't you?
Anyway, we already make this call in SolrDispatchFilter - if anything, we
should simply ensure we only call it once. Not that it will buy us any
performance.
It's not a call we need to strive to avoid calling on any Solr request though.
> CloudSolrServer can query the wrong replica if a collection has a SolrCore
> name that matches a collection name.

> spin off of SOLR-2894 where sarowe & miller were getting failures from
> TestCloudPivot that seemed unrelated to any of hte distrib pivot logic itself.
> in particular: adding a call to "waitForThingsToLevelOut" at the start of the
> test, even before indexing any docs, seemed to work around the problem -- but
> even if all replicas aren't yet up when the test starts, we should either get
> a failure when adding docs (ie: no replica hosting the target shard) or
> queries should only be routed to the replicas that are up and fully caught up
> with the rest of the collection.
> (NOTE: we're specifically talking about a situation where the set of docs in
> the collection is static during the query request)
