Hey all, I'd like to start a discussion about supporting schema evolution on Iceberg branches, as there are some interests and some discussions around this feature.
Would appreciate feedback on this proposal doc <https://docs.google.com/document/d/1yzE3Mm_ZALdWv_5HlMlGL0sk4-G4zU9oqxdo2ufQi3I/edit?tab=t.0#heading=h.g7zu7nim8ekj> and here is the Draft PR <https://github.com/apache/iceberg/pull/15012> for the high level direction I am going. Best, Yingjian
