+ ``SessionContext`` can automatically resolve SQL table names that match
+ in-scope Python data objects. When automatic lookup is enabled, a query
+ such as ``ctx.sql("SELECT * FROM pdf")`` will register a pandas or
+ PyArrow object named ``pdf`` without calling
+ :py:meth:`~datafusion.SessionContext.from_pandas` or
+ :py:meth:`~datafusion.SessionContext.from_arrow` explicitly. This requires
+ the corresponding library (``pandas`` for pandas objects, ``pyarrow`` for
+ Arrow objects) to be installed.
Review Comment:
For both, this should use the Arrow PyCapsule Interface, no? Then you don't
need any specific dependency because Pandas objects will by definition already
have Pandas installed.
