Hi Hongbo, Thanks for the +1. Including #10536 and #10552 sounds good to me.
The Iceberg fix is now on release-2.1 ( https://github.com/apache/paimon/pull/10644, thanks Jingsong). I tried both PyPaimon fixes on release-2.1: - #10536: the backport is https://github.com/apache/paimon/pull/10669. It needed two small test fixes that master got later, in #10548 and #10552, which are described in the PR. - #10552: its tests conflict, because they rely on changes from #10436 and #10393 that aren't on release-2.1. Could you or the author take this backport? CI on release-2.1 has two problems that will affect every Python backport: - Python 3.6 and 3.7 fail because readerwriterlock 1.0.10, released on Oct 13, needs Python 3.8. Master fixed this in #10532, so release-2.1 needs that too; I can open the backport. This also affects users installing PyPaimon 2.1.0 on Python 3.6 or 3.7. - Python / Native CI builds paimon-rust from main, which has moved since release-2.1 last passed it on Oct 8. 27 native write and deletion vector tests now fail regardless of the change. Would you be willing to act as release manager for 2.1.1? I'll test the release candidate when the vote starts.
