Yeah, I understand and XA protocol in SQL layer was introudced by https://github.com/apache/shardingsphere/pull/14075. But I think we still need to handle XAStatement in sharding-proxy especially in the case of crash recovery happening in the multi backend databases. I think we don’t have any test case for this scenario currently.

Anyway my +1 for improving the implementation of TransactionXAHandler but no just deleting it.

no doubt that XA is stands for distribution transaction. I think we just need to figure out how to distinguish between handle it automatically or manually.
