@flashJd it seems that this is trying to address both scan planning and CDC read. might be easier to separate them out.

Regarding scan planning, I just created a new PR #4580 on adding a new IncrementalTableScan interface. Would love to get your feedbacks and see if we can align on the effort.

also how is this one different with PR #3095 mentioned in the description?
