----------------------------------
Hi [~dianfu], a quick update: Liu Liu and I have agreed to continue FLINK-40471
through their existing PR #29048 (https://github.com/apache/flink/pull/29048).
I have closed #29470 to avoid duplicate work. Could you please reassign the
issue to [~auroflow]? Thanks again for assigning it to me and clarifying the
scope.
