@Iddo Avneri Is Iceberg "smart merge" capability sill on the table ? I came across your post here :

Since OTFs hold the table level changes, lakeFS can utilize this knowledge to provide highly elaborated diff operations, and smart merge capabilities.

But then that "smart merge capabilities" seems to be "out-of-scope" : https://github.com/treeverse/lakeFS/issues/3381

Yes, it most certainly is. It's on the roadmap.
