> 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. The 
> functionality for determing the schema is already available in the Python 
> code, it is at moment just very tightly bound to the conversion 
> infrastructure.
