> [@zero-element](https://github.com/zero-element) [@steven-luabase](https://github.com/steven-luabase) Have you [looked into `union-by-name`](https://py.iceberg.apache.org/api/#union-by-name)? This will allow for schema evolution. You could wrap it in the same transaction.你是否查看了 `union-by-name` ？这将允许模式演化。你可以将它包装在同一个事务中。 @Fokko It seems that union_by_name is primarily used for schema alignment rather than for upserting data from another table into an existing one. I'm not sure if I've misunderstood anything, but the latter is what I actually need. -- This is an automated message from the Apache Git Service.
