> This is an umbrella jira to track all individual issues, bugfixes and small
> optimizations around MetaCache (region locations cache) in the client.
> Motivation is that under the load one could see a spikes in the number of
> requests going to meta - reaching tens of thousands requests per second.
> That covers issues when we clear entries from location cache unnecessary, as
> well as when we do more lookups than necessary when entries are legitimately
> evicted.
