The Delta Table created as a result of the Dataframe returned by @dlt.create_table is confirmed to be overwritten when checked with the DECREASE HISTORY command.
I want this to be handled as a CRAS, or CREATE AS SELECT, but how can I do this in python code?

If you don't mind me asking, can I see the code or documentation for this? I searched for DelataTableBuilder and only found Scala related stuff.

Hi @rt-slowth You can review this open source code base of Delta to know more about the DeltaTableBuilder's implementation in Python.
