# Proposed changes Normally, in 2pc, commit cannot fail, otherwise it will cause data loss. But sometimes, when resuming a task from checkpoint, the txnid recorded in the checkpoint may have expired. At this time, an error txn not found will be reported, including some other unexpected errors. At this time, the offset of the source saved by ckpt cannot be used. If the txn is submitted successfully, the first commit failure can be tolerated. Therefore, the parameter `sink.ignore-commit-error` is added. Usually used in 2pc failure recovery, the default is false. If the checkpoint encounters an unrecoverable scenario (such as txn not found), you can temporarily turn on the recovery, and then close the configuration after the checkpoint is normal. ## Checklist(Required) 1.
