Hi Dev and User, Blink planner for Table API & SQL is introduced in Flink 1.9 and already be the default planner for SQL client in Flink 1.10. And since we already decided not introducing any new features to the original Flink planner, it already lacked of so many great features that the community has been working on, such as brand new type system, more DDL support and more planner capabilities. During this time, we've also received lots of great feedback from users who were trying to use blink planner, both positive and negative (like bugs). This is a good sign, it at least shows more and more users are starting to try out.
So I want to start this discussion more formally to talk about replacing the default planner to blink. Specifically, I want to gather feedbacks from dev and user about whether blink planner already cover the original planner's capabilities, what kind of issues you've ran into when try out blink planner and then make you fallback to original one. Since there is still a month to go when feature freeze, there's still enough time for community to further enhance blink planner for this purpose. Let me know what you think, especially if you want to report or complain about something. Thanks in advance. Best, Kurt
