Message Broker
In Bale Messenger’s golang backend trainee program, as our final project, we were tasked to implement a gRPC message broker. In this project I had hands-on experience working with:
- Channels / Lock / Mutex
- grpc/Protobuf
- Postgres & SQL
- Load testing
- Unit testing
- Load Testing using K6 and custom written golang client
- Tracing using Jaeger
- Performance scrapping using prometheus
- Performance monitoring using custom-built Grafana dashboards
- Global and local rate limiting using envoy
- Containerization and container orchestration using Kubernetes
- Performance optimization using insert batching and in-memory caching
Performance Report
We had several load testing and stress testing phases on broker's publish functionality using K6 and custom-built golang clients.
