SQL catalogs for Flink
Cloudera Streaming Analytics supports Hive, Kudu and Schema Registry catalogs to provide metadata for the stored data in a database or other external systems. You can choose the SQL catalogs based on your Flink application design.
For more information about Flink Catalogs, see the Apache Flink documentation.
A generic in-memory catalog is enabled by default. However when the in-memory catalog is used, all objects are only available for the lifetime of the session.
