Thank you @liurenjie1024 . I have looked the doc @sdd mentioned that describes Iceberg column projection. Looks like the projection is specified by field id as @sdd said due to schema evolution. I think at user API, I guess it should be selected by column names. For example, currently in `TableScanBuilder` the API `select` is used to select columns by names. And we find the field ids internally by column names and use matched field ids to do column projection. But currently the `select` API cannot select deeply nested fields. It is also in #251 or #252? I will take a look #251 and #252 and see if I can implement them first. -- This is an automated message from the Apache Git Service.
