> Is this a typo: t1 -> t4? Yeah, thanks @stevenzwu. It's a typo, sorry for that. > It have to re-apply all the expensive rewrite computation based on the latest snapshot. Re-do the expensive rewrite process is not the solution that people want because if the streaming job is checkpointing for every 1min and the rewrite action take 4min to complete , then there is probability that the expensive rewrite action will be always retrying. Besides the expensive resource cost from retrying, there is a data semantic issue that will confuse people much. I mean different txn commit order between RewriteFiles and CDC/Upsert transaction will lead to different data set for the same dataset & operations. Then people won't trust the truth of iceberg table. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
