David Balamber commented on NIFI-3641:
--------------------------------------

Are there any plans to improve the current InvokeGRPC and ListenGRPC 
processors, so that they could take any .proto file to communicate with a 
third-party gRPC server that uses a specific Protobuf message definition?

> "gRPC is a modern open source high performance RPC framework that can run in 
> any environment. It can efficiently connect services in and across data 
> centers with pluggable support for load balancing, tracing, health checking 
> and authentication. It is also applicable in last mile of distributed 
> computing to connect devices, mobile applications and browsers to backend 
> services." [1]
> It would be useful to be able to interact with gRPC services in NiFi.  A 
> first step would be to have a processor that can take a .proto file or files 
> and then use the generated code to talk to a gRPC server.  Having a 
> Site-To-Site gRPC implementation could also be useful though as it should be 
> very easy to port to any of the supported platforms. [2]
> This should allow us to interact with Tensor Flow among other things.
