Is it safe to assume that given host/port values, JDBC driver will only call [host]:[port]/arrow.flight.protocol.FlightService/[MethodName]?

Context: I need to configure proxy to be able to route JDBC driver traffic to the FlightSqlServer.

Unfortunately no... a getFlightInfo call can return a different Location for the corresponding getStream call, which could include a different host and port. You can read more about that here: https://arrow.apache.org/docs/format/Flight.html#downloading-data and https://arrow.apache.org/docs/format/Flight.html#extended-location-uris
