    Description

      Currently, every table metadata change (DDL/DML operation) causes the catalog to serialize the entire table metadata and send it to: a) the impalad node that triggered the operation and b) all the impalad nodes via a statestore update. The catalog should instead send only the portion of the table metadata that changed. Furthermore, certain operations, like DESCRIBE statements, don't require the full table metadata.
