hi Ming, See comment on the FlightDescriptor member of FlightData:
https://github.com/apache/arrow/blob/master/format/Flight.proto#L281 The descriptor can contain a serialized CMD if you need to pass additional information to the server when you are starting a DoPut operation. The schema is found in the first RPC message FlightInfo contains the "query plan" for accessing a possibly distributed dataset so really only makes sense for the DoGet RPC. Hope this helps Wes On Fri, May 24, 2019 at 8:18 PM ming zhang <ming.zhang.ch...@gmail.com> wrote: > > hi > > wonder how to understand current doput() call. the doget() call pass the > flightinfo as the parameter. does it makes sense to also pass flightinfo as > part of the doput() call? > > thanks > ming
