WebSep 1, 2024 · Two-phase commit (TPC) [26] offers ACID, serializable transactions but imposes blocking operations across functions participating in a transaction, which penalizes performance in return for strict atomicity. Apparently, distributed transactions and the Saga pattern serve opposing goals. WebThis is a recommended base class for all of the SinkFunction that intend to implement exactly-once semantic. It does that by implementing two phase commit algorithm on top of the CheckpointedFunction and CheckpointListener. User should provide custom TXN (transaction handle) and implement abstract methods handling this transaction handle.
