For the purpose of clarity, examples in this chapter are written in Python as one of the supported scripting languages and in Java. Instead, the implementation queues the RPCs until the channel is READY. it uses gRPC (protocol buffer for the on-the-wire encoding, and HTTP/2 as the transport) that adds extra features such as the possibility to set watches to get notified on changes. Perquisites This requires Go…. gRPC-Node的功能库,用于打包. // GRPC calls are synchronous, but some callbacks expect to be called asynchronously // (eg. If a StreamHandler returns an error, it should be produced by the status package, or else gRPC will use codes.
