> I want to cast pyarrow table column from decimal(38,4) to int64.
> col.cast(pa.int64())
> Error:
>  File "pyarrow/table.pxi", line 443, in pyarrow.lib.Column.cast
>  File "pyarrow/error.pxi", line 89, in pyarrow.lib.check_status
>  pyarrow.lib.ArrowNotImplementedError: No cast implemented from decimal(38, 4) to int64
> Python version : 3.6.5
>  Pyarrow version : 0.10.0
> is it not implemented yet or I am not using it correctly? If not implemented yet, then any work around to cast columns?
