Krisztian Szucs commented on ARROW-1993:
----------------------------------------
[~xhochy] the PR seems incomplete and abandoned, should We delay it to 0.12 or
reimplement it?
> [Python] Add function for determining implied Arrow schema from

> 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.
> 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.
