[jira] [Created] (ARROW-16518) [Python] Ensure _exec_plan.execplan preserves order of inputs

Alessandro Molina created ARROW-16518:
-----------------------------------------

             Summary: [Python] Ensure _exec_plan.execplan preserves order of inputs
                 Key: ARROW-16518
                 URL: https://issues.apache.org/jira/browse/ARROW-16518
             Project: Apache Arrow
          Issue Type: Sub-task
          Components: Python
            Reporter: Alessandro Molina
             Fix For: 9.0.0


At the moment execplan doesn't guarantee any ordered output, the batches are consumed in a random order. This can lead to unordered outputs when `use_threads=True`
