Motivation

In our production, we create Flink Session Cluster and users can perform OLAP query in it. Users like to use Jdbc Driver in their applications to submit queries and get results. Currently we use the old flink-sql-gateway[1] and flink-jdbc-driver[2],  but when we try to upgrade our Flink Session Cluster, We meet compatibility problem. Flink Sql Gateway has been a submodule in Flink code base, and the API has been greatly optimized. The old Flink JDBC Driver cannot connect to the new Gateway directly which cause we cannot upgrade our Flink version. In this FLIP, I'd like to introduce Flink Jdbc Driver module in Flink to connect Gateway, users can use Jdbc Driver to submit their queries and get results like a database in their applications.
