Description

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.
