Hi, +1
I agree with jacky, we can store Info in table metadata. But here one problem we can face, that is metastore connection issue. If there are lot of tables and datamaps, doing many connection to metastore reduces performance. In this case reading from one schema file will be better. So if we are planning to store in metadata, then better while refactoring we need to take care of almost reducing the metastore connection for getting info of datamaps until and unless table is altered or any other similar scenario.
