### Describe the enhancement requested With apache/arrow#36155, implementations of Flight RPC may not return quickly via a newly added `pollFlightInfo` function. Sometimes, the system implementing this function may not know the output schema for some time--for example, after a lengthy queue time as elapsed, or after planning. In proto3, fields may not be present, and it's a coding convention to require them [^1]. To support upcoming client integration work for `pollFlightInfo`, the `schema` field can be made optional so that it's not a requirement to populate the `FlightInfo`'s schema on the first `pollFlightInfo` request. We can modify our client code to allow this field to be optional. This is already the case for the Go code.
