[jira] [Created] (ARROW-2074) [Python] Allow type inference for struct arrays

Antoine Pitrou created ARROW-2074:
-------------------------------------

             Summary: [Python] Allow type inference for struct arrays
                 Key: ARROW-2074
                 URL: https://issues.apache.org/jira/browse/ARROW-2074
             Project: Apache Arrow
          Issue Type: Improvement
          Components: Python
            Reporter: Antoine Pitrou
            Assignee: Antoine Pitrou


Support inferring a struct type in a {{pa.array}} call, if a sequence of dicts (or dict of sequences?= is given. Of course, this could mean that the wrong field order may be inferred, though on Python 3.6+ dicts retain ordering until the first deletion.
