    Description

      Git issue LInk : https://github.com/apache/arrow/issues/2627

      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?
