> The FullUpdateInitializer follows the {{MetastoreCacheInitializer}}. It reads a bunch of information from HMS and uses Thrift structures to pass around, but in the end it just constructs {{Map<String, Set<String>>}}. It uses concurrent fetches from HMS, but synchronizes a lot on common data structures to update them.
> I think that we can refactor all this code to make it faster and consume less memory. The idea is the following:
> Use background threads to collect Thrift results from HMS calls (database, table and partition data). Then we can use a single thread to construct the resulting update and return it without using intermediate Thrift methods.
