Mark Miller commented on SOLR-6379:
-----------------------------------
bq. The querystring is parsed for 100% of requests just to figure this out. it
is too expensive. We should avoid the extra query parsing
That's an isolated point that can be addressed. The cost of that is going to be
negligible, but even if that was not the case, it's a small part of this patch.
bq. This is clearly a corner case.
Sorry - I'm dedicated to supporting corner cases too.
bq. our core APIs will be crippled in the future when the legacyCloud=false
kicks
Can you back that claim up with facts?

> 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)
