# Which issue does this PR close? - related https://github.com/apache/datafusion-python/issues/875 # Rationale for this change A top level cast is very practical and a common practice to do, since it's just a projection of columns, we call with_columns underneath. Therefore it builds on top of: https://github.com/apache/datafusion-python/pull/909, so that one needs to be merged first. # What changes are included in this PR? - adds a `cast` method which takes in a mapping of col_names and dtypes. Important: I am going to work soon on creating a datafusion-python native schema struct and classes. Because going to pyarrow is simply to painful :) and then we can also drop the pyarrow dependency for that part # Are there any user-facing changes? - adds new method. -- This is an automated message from the Apache Git Service.
