Usually, interface describes behavior and expose methods, which designed be called from outside the class. Here, `newTableDescriptor` and `newTableVersion` are not designed to be called from the outside, they niether change any state, nor their result is usable outside the class. Actually, interface mixes 2 responsibilities: a catalog command and descriptor factory. E.g. the factory can be passed to command via constructor. -- This is an automated message from the Apache Git Service.
