[jira] [Created] (ARROW-14060) [Python] Allow Table.from_pydict to specify a type mapper for extension types

Weston Pace created ARROW-14060:
-----------------------------------

             Summary: [Python] Allow Table.from_pydict to specify a type mapper for extension types
                 Key: ARROW-14060
                 URL: https://issues.apache.org/jira/browse/ARROW-14060
             Project: Apache Arrow
          Issue Type: Improvement
          Components: Python
            Reporter: Weston Pace
            Assignee: Weston Pace


An example use case would be registering a type mapper that maps from UUID to a custom extension type or registering an extension type for `complex`.  However, it could be used for builtin types as well (e.g. mapping all `int` to `pa.int8()`)
