Hi Paimon community, I would like to start a discussion about supporting Data Evolution for BLOB columns.
The main problem is that updating BLOB columns may introduce huge overhead if unchanged BLOB values need to be copied into newly generated files. I prepared a design document to describe the background, possible approaches, and open questions: I prepared a short design document here with 2 proposals: https://docs.google.com/document/d/1KXIuN6_haY-Hqy-gNu9x_DFpAnmu4OzkmcKMJWssN8k/edit?usp=sharing Could you please take a look and share your thoughts? Best, Wang
