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