What does this PR address?
This PR adds support for serializing Pandas DataFrames in both the Arrow IPC File and Streaming Formats. These formats are faster than Parquet from a serialization/deserialization perspective at the cost of a larger payload. This is a tradeoff which will depend on network bandwidth.
Additionally, it is worth noting that this PR uses the officially registered mime types for Arrow:
https://www.iana.org/assignments/media-types/application/vnd.apache.arrow.file
https://www.iana.org/assignments/media-types/application/vnd.apache.arrow.stream
It is a shame that BentoML doesn't use the correct mime type for Parquet - perhaps that is something to tackle in another PR:
https://www.iana.org/assignments/media-types/application/vnd.apache.parquet
