Effective in version 10.4.0, you can create a JDBC V2 connection to connect to Aurora PostgreSQL, Azure SQL Database, or any database that supports the Type 4 JDBC driver. You must select the required database subtype in the JDBC V2 connection properties. You can use the JDBC V2 connection in mappings to read from or write data to databases with the Type 4 JDBC driver. You can validate and run JDBC V2 mappings in the native environment or in the non-native environment. In the non-native environment, you can run mappings on the Spark engine in the Hadoop environment, or on Databricks.
