Provide non blocking getFlightInfo #719
Description
Describe the enhancement requested
We have a use case in our production environment where getFlightInfo can take longer than a second and having a blocking getFlightInfo is a problem. Since many other methods in FlightProducer is non blocking we should also have a non blocking getFlightInfo
The code would look something like this with minimum impact to all the implementations
/**
* Get information about a particular data stream.
*
* @param context Per-call context.
* @param descriptor The descriptor identifying the data stream.
* @return Metadata about the stream.
*/
FlightInfo getFlightInfo(CallContext context, FlightDescriptor descriptor);
/**
* Get information about a particular data stream.
*
* @param context Per-call context.
* @param descriptor The descriptor identifying the data stream.
* @param listener An interface for sending data back to the client.
*/
default void getFlightInfo(CallContext context, FlightDescriptor descriptor, StreamListener<FlightInfo> listener ){
FlightInfo flightInfo = getFlightInfo(context, descriptor);
listener.onNext(flightInfo);
listener.onCompleted();
}
/**
*
* @return true if blocking (default) version of getFlightInfo needs to be used by FlightService.
*/
default boolean isBlockingFlightInfo() {
return true;
