Motivation

Flink Jdbc Driver is used to submit queries to SqlGateway. There are The old repositories flink-sql-gateway[1] and flink-jdbc-driver[2] which support submitting query to older flink cluster version. But for the latest flink version there are compatibility problems. Flink Sql Gateway has been a submodule in Flink, and the API has been greatly optimized. The old Flink JDBC Driver cannot connect to the new Gateway directly which cause we users cannot upgrade our their Flink versionClusters. In this FLIP, Iwe'd like to introduce Flink Jdbc Driver module in Flink to connect the new Gateway, users can use Jdbc Driver to submit their queries and get results like a database in their applications.
