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. 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.
