This example flight service stores uploaded Arrow tables in memory.

First, create a new gRPC service (Flight is based on gRPC):

dotnet new grpc

Delete the example greeter service.

Then, implement a concrete subclass of FlightServer. See ./Services/InMemoryFlightServer.cs.

Finally, in ./Program.cs add the Flight server to the gRPC services and map the endpoints with the extension methods:

grpcBuilder.AddFlightServer<InMemoryFlightServer>();
...
app.MapFlightEndpoint();
