Learning Apache Flink S01E06: The Flink JDBC Driver
Read OriginalThis technical article investigates how to connect to Apache Flink using JDBC. It explains the two available options: the new Flink JDBC driver (introduced in version 1.18) which uses the SQL Gateway's REST endpoint, and the Hive JDBC driver which connects via the SQL Gateway's HiveServer2 endpoint. The post contrasts the drivers, discusses the role of the SQL Gateway, and touches on the importance of catalogs like HiveCatalog for persistent metadata.
