Arrow Flight SQL JDBC Driver and RPC calls

[merzbird]

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.
