[jira] [Created] (ARROW-13696) [Python] Support for MapType with Fields

Jason Reid created ARROW-13696:
----------------------------------

             Summary: [Python] Support for MapType with Fields
                 Key: ARROW-13696
                 URL: https://issues.apache.org/jira/browse/ARROW-13696
             Project: Apache Arrow
          Issue Type: Improvement
          Components: Python
    Affects Versions: 5.0.0
            Reporter: Jason Reid


Ability to create a [MapType|https://arrow.apache.org/docs/python/generated/pyarrow.map_.html] object passing Field types instead of DataTypes for the key_type and item_type arguments.  Something similar to what is possible for [ListType|https://arrow.apache.org/docs/python/generated/pyarrow.list_.html#pyarrow.list_] in python or what seems to be possible from the [cpp implementation of MapType|https://github.com/apache/arrow/blob/master/cpp/src/arrow/type.cc#L424] (untested).
