XiaoHongbo-Hope opened a new pull request, #9881: URL: https://github.com/apache/paimon/pull/9881
Concurrent PyArrow S3 renames can overwrite an existing snapshot or schema file after both writers observe it missing. For PyArrow 22+, publish metadata with conditional PutObject (`If-None-Match: *` on S3, `x-oss-forbid-overwrite` on OSS). Reject versioned OSS buckets because OSS ignores that header there. Verified concurrent S3/OSS writes against a local HTTP endpoint with PyArrow 22/23 and boto3 1.36/1.43. Depends on #9821; older PyArrow versions retain the existing path. -- This is an automated message from the Apache Git Service.
