Hi paimon team, I'd like to propose a 2.1.1 patch release for an Iceberg compatibility bug in 2.0.0 and 2.1.0.
With Iceberg compatibility enabled, the snapshot summary that Paimon writes undercounts total-data-files, total-records and total-files-size, and they can drop to 0 while the manifests still have live files. Iceberg readers that rely on these fields can decline to refresh the table, so users of Iceberg compatibility can't safely upgrade to 2.x until a release includes the fix. The fix was merged to master in https://github.com/apache/paimon/pull/10575 (issue https://github.com/apache/paimon/issues/10574). Tables that already have wrong totals are corrected on their next commit. The backport to release-2.1 is https://github.com/apache/paimon/pull/10644. It cherry-picks cleanly, and the Iceberg tests in paimon-core and paimon-iceberg pass on the branch. If there are other fixes that should go into 2.1.1, please reply to this email. I'm happy to help test the release candidate. Thanks Best, Karan
