Uwe L. Korn updated ARROW-1993:
-------------------------------
Description:
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.
We should provide the user a function {{pyarrow.Schema.from_pandas}} which
takes a DataFrame as an input and returns the respective Arrow schema.
