Spanner supports these JDBC drivers:
- The Spanner JDBC driver, which is an open-source JDBC driver that is written, provided, and supported by Google, similar to the Cloud Client Libraries. This is the recommended JDBC driver for Spanner, especially for the GoogleSQL dialect. You can also use it to connect to PostgreSQL-dialect databases.
- The PostgreSQL JDBC driver in combination with PGAdapter. This driver only supports PostgreSQL-dialect databases.
