> Hive Calcite metadata providers are compiled when the 1st query comes in.
> If a second query arrives before the 1st one has built a metadata provider,
> it will also try to do the same thing, because the cache is not populated yet.
> With 1024 concurrent users, it takes 6 minutes for the 1st query to finish
> fighting all the other queries which are trying to load that cache.
