A flight js service is a (non-proper) extension of arrow flight service that augments existing client-streaming (or bidirectional streaming) methods with a pair that can be used to simulate a client stream over unary requests.
rpc NextDoExchange (, )
BrowserFlight.proto:60rpc NextDoPut (, )
BrowserFlight.proto:50rpc NextHandshake (, )
BrowserFlight.proto:39rpc OpenDoExchange (, stream )
BrowserFlight.proto:59Open a bidirectional data channel for a given descriptor. This allows clients to send and receive arbitrary Arrow data and application-specific metadata in a single logical stream. In contrast to DoGet/DoPut, this is more suited for clients offloading computation (rather than storage) to a Flight service.
rpc OpenDoPut (, stream )
BrowserFlight.proto:49Push a stream to the flight service associated with a particular flight stream. This allows a client of a flight service to upload a stream of data. Depending on the particular flight service, a client consumer could be allowed to upload a single stream per descriptor or an unlimited number. In the latter, the service might implement a 'seal' action that can be applied to a descriptor once all streams are uploaded.
rpc OpenHandshake (, stream )
BrowserFlight.proto:38Handshake between client and server. Depending on the server, the handshake may be required to determine the token that should be used for future operations. Both request and response are streams to allow multiple round-trips depending on auth mechanism.
