Hi all， I am currently learning table API and SQL in Flink. I noticed that Flink does not support Hive tables as table source, and even JDBC table source are not provided. There are cases we do need to join a stream table with static Hive or other database tables to get more specific attributes, so how can I implements this functionality. Do I need to implement my own dataset connectors to load data from external tables using JDBC and register the dataset as table, or should I provide an external catalog?
Thanks, wangsan
