[jira] [Created] (ARROW-1250) [Python] Define API for user type checking of array types

Wes McKinney created ARROW-1250:
-----------------------------------

             Summary: [Python] Define API for user type checking of array types
                 Key: ARROW-1250
                 URL: https://issues.apache.org/jira/browse/ARROW-1250
             Project: Apache Arrow
          Issue Type: New Feature
          Components: Python
            Reporter: Wes McKinney


We have some subclasses of {{pyarrow.lib.DataType}}, but we haven't been designing with the intent of writing {{isinstance(arr.type, pyarrow.TimestampType)}}. We should think about the public API for such type-checking or other type of schema validation.
