gRPC Bidirectional Streaming for a C++ Node-Graph Framework

Thu, 01 Jan 1970 00:33:44 +0000

Nova Sonic needed the speech framework’s pipelines delivered as a containerized gRPC service: audio and system prompts streaming in, inference requests streaming out. The team’s code had only ever been called through JNI.
Mapped gRPC C++’s bidirectional-streaming reactor onto the framework’s pipe abstraction once, as a reusable layer covering session setup and teardown, signal handling, graceful error handling and logging.
A new service needs under 300 lines of integration code: which pipe input receives request messages, and which pipe outputs become response messages. Adopted org-wide as the standard way to deploy a pipeline.
Established Protobuf and gRPC generated code as first-class CMake libraries in the framework’s build, so the same generated types are consumed by the pipeline’s nodes and by the server without duplicate-symbol conflicts.
