Hi, I'm implementing a custom Catalog where for "create table" I need to get tables schema, both column names and types from DDL.
Now the Catalog's createTable method has "CatalogBaseTable table" argument. The CatalogBaseTable has a deprecated "getSchema" and suggest to use getUnresolvedSchema instead. I was able to resolve schema types for physical columns, but I'm struggling with computed columns [1]. To be more precise I'm struggling to get//resolve the type of this field. I see that all implementations that would be needed to resolve inderlying expression of UnresolvedComputedColumn are marked as @Internal. On the other hand the deprecated "getSchema" has a proper type for this ComputedColumn. I'm wondering now, what should I do. Should I use the deprecated API that has what I need already or should I use suggested API and somehow try to resolve the type using @Internal classes which also does not seems safe. I would appreciate for any hint here.
