@DriverCapability(prefix="tee",

                  capabilities="replication")
@DriverSideEffects(stateful=true)
public class TeeDriver
extends AbstractProxyDriver

Replicates write operations across multiple database connections.

TeeDriver sends all operations to two database connections simultaneously, useful for scenarios like:

• Write replication to a secondary database
• Dual-write during migration periods
• Keeping audit databases in sync

Warning: TeeDriver does not provide transactional guarantees across the two connections. If one write succeeds and the other fails, the databases will be inconsistent.

URL format: jdbc:tee:jdbc:target1:...;jdbc:target2:...

Example:

 jdbc:tee:jdbc:postgresql://primary/db;jdbc:postgresql://replica/db
