XiaoHongbo-Hope opened a new pull request, #9888: URL: https://github.com/apache/paimon/pull/9888
PyArrow S3 `move()` can overwrite an existing snapshot or schema after concurrent writers both see the key as absent. This predates #9821. Use signed conditional `PutObject` for S3 and OSS metadata commits. OSS buckets with versioning are rejected because OSS ignores its overwrite guard there; OSS credentials need `GetBucketVersioning` permission. Tests: concurrent S3/OSS writes, cross-bucket routing, signed headers, versioning and permission failures. Passed on Python 3.6/PyArrow 6 and PyArrow 18, 22, 23; FileIO/catalog tests and lint passed. Real OSS/DLF was not run. -- This is an automated message from the Apache Git Service. To respond to the message, please log on to GitHub and use the URL above to go to the specific comment.
