Driver

@DriverCapability(prefix="sink",
                  description="Discards all SQL operations",
                  capabilities="testing",
                  terminal=false)
public class SinkDriver
extends AbstractProxyDriver

Discards all SQL operations without executing them.

SinkDriver is useful for:

• Benchmarking driver overhead without database I/O
• Testing connection logic without a real database
• Dry-run scenarios where SQL should be generated but not executed

All execute methods return success without actually running SQL. Query methods return null ResultSets.

URL format: jdbc:sink:jdbc:target:...

Example:

 jdbc:sink:jdbc:postgresql://localhost/mydb
