> Design considerations:
> 1) Cache is *not blocked* for updates during index creation.
> 2) DDL thread flow:
> - Create index and add it to some collection of pending indexes;
> - Iterate over all cache entries and add them one by one;
> - Once iteration finished - add index to the table;
> 3) Cache thread flow:
> - If there are any pending index, then propagate update to the index.
> Be careful with put/remove interleaving.
