Review Comment:
Consider directly throw exception when some config is not available.
Please also add a TODO to remove this method because we should never read ZK
at query path.

This is not really a manager. You may call it LogicalTableConfigs

Review Comment:
I'd suggest just keeping the plain map. Each class introduced is adding
overhead on heap. Putting some javadoc explaining what each level stands for
should be good enough.

Some of the map can be optimized into Pairs to reduce overhead

Review Comment:
Why each physical table is wrapped as an implicit hybrid table? We should
have an abstraction for single physical table
