Yeah so I didn't know about Arrow and I'm glad I looked it up (while trying to figure out what exactly was going on), it's a really cool technology. A lot of server time is spent encoding/decoding JSON -- but wonder if it could help that use-case? I know how to compare thrift/protobuf/cbor/etc but I don't really know if Apache can work for the general use case -- it seems like it deals in tables and sets.

Most of the time I don't necessarily want disparate languages in one system but it seems inevitable and knowing that Arrow exists seems like it will help me one day.
