hi iceberg dev: Kyle and I have recently done some work on Iceberg Flink New Sink, PR is https://github.com/apache/iceberg/pull/4904 preliminary proposal: https://docs.google.com/document/d/1G4O6JidAoKgbIdy8Ts73OfG_KBEMpsW-LkXIb89I5k8/edit?usp=sharing
It refactors our flink writer topology based on Flink's unified Sink(FLIP-143 & FLIP-191). It sets the stage for adding small files and index files later. Could anybody have a chance to help to review and give some opinion? Thank you so much to Junjie for the first round review. Thanks in advance.
