      Description

      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.
