Hi! @RussellSpitzer, the table schema is shared globally across all branches. While data writes are isolated to a specific branch, any ALTER TABLE … ADD COLUMN operation updates the schema for every branch, including main. Currently, if I want to experiment on a production Iceberg table without duplicating the data and without impacting the production table itself, that isn’t possible. Having the ability to clone a table would solve this. It would let me create a (data) zero-copy clone of a production Iceberg table and run experiments safely, without affecting the original production table. -- This is an automated message from the Apache Git Service.
