Description

The TableEnvironment holds an internal table catalog to provide SQL and Table API queries access to structured data. At the moment, DataSets, DataStreams, and TableSources which refer to external tables can be registered as tables.

This issue proposes to implement an interface to connect external catalogs such as Hive's HCatalog or Confluent's SchemaRegistry for Apache Kafka to the TableEnvironment. With this interface, it should be possible to look-up and access tables which are registered in external catalogs.
