Jark Wu updated FLINK-16887:
----------------------------
Description:
Current retraction machanism only support 2 message kinds (+ and -). However,
since FLIP-95, we will introduce more message kinds to users
(insert/delete/update_before/update_after).
In order to support that, we should first refactor current retraction rules to
support ChangelogMode inference. In previous, every node will be attached with
a AccMode trait after retraction rule. In the proposed design, we will infer
ChangelogMode trait for every node.
