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.
