[jira] [Created] (ARROW-1993) [Python] Add function for determining implied Arrow schema from pandas.DataFrame

-----------------------------------

             Summary: [Python] Add function for determining implied Arrow schema from pandas.DataFrame
                 Key: ARROW-1993
                 URL: https://issues.apache.org/jira/browse/ARROW-1993
             Project: Apache Arrow
          Issue Type: Improvement
          Components: Python
            Reporter: Wes McKinney


Currently the only option is to use {{Table/Array.from_pandas}} which does significant unnecessary work and allocates memory. If only the schema is of interest, then we could do less work and not allocate memory
