Module arrow_flight::sql::server

Helper trait FlightSqlService for implementing a FlightService that implements FlightSQL.

Structs

• PeekableFlightDataStream
  A wrapper around Streaming<FlightData> that allows “peeking” at the message at the front of the stream without consuming it. This is needed because sometimes the first message in the stream will contain a FlightDescriptor in addition to potentially any data, and the dispatch logic must inspect this information.

Traits

• FlightSqlService
  Implements FlightSqlService to handle the flight sql protocol
