And it implements CICD based on Jenkins/Gitlab/Harbor. Core nuget package). The gRPC server reflection can be used by the client to determine the methods and types expose in the gRPC server. For example, liveness probes could catch a deadlock, where an application is running, but unable to make progress. Example: Standardize response formats to include metadata and data fields consistently. The ideal number of completion queues in relation to the number of threads can change over time (as gRPC C++ evolves), but as of gRPC 1. Based on the pioneering research presented in Accelerate, these four key metrics—deployment frequency, lead time for changes, change failure rate, and mean time to recovery (MTTR)—offer a quantifiable glimpse into the performance and health of Metadata. The question is: I need to port ~100 queries. proto files define your API contract. Chapter 4: Performance Best Practices for Using gRPC on .

If you see this often, then we There can only be one read and one write in flight at a time This is an API requirement rather than a best practice, but worth mentioning again. 23. NET by applying logging and metrics A guide to best practices for running liveness probes in Kubernetes clusters as a health check to determine if a container is still running and responsive. Here’s a blog post with some explanation. proto file that defines a simple gRPC service for greeting users: OP conflates gRPC with protobufs -- they are not the same and in fact almost entirely separable (gRPC does use protobufs for some low-level protocols but that's mostly internal to the implementation). gRPC takes the stress out of failures! Get fine-grained retry control and detailed insights with OpenCensus and OpenTelemetry support. If you are using grpc-netty, add a runtime dependency on io.
