Overview
RustPulse is a production-oriented telemetry engine built in Rust.
It is designed to explore how real-world systems behave under constraints such as:
- intermittent connectivity
- partial failures
- distributed ingestion
- observability requirements
It focuses on reliability, system design, and engineering discipline, not just feature development.
What this project demonstrates
RustPulse is built as a proof of production readiness:
- real ingestion flow via a Rust CLI agent (no mock-only system)
- hexagonal architecture (clear separation of concerns)
- CI pipeline (fmt, clippy, tests, coverage, dependency audit)
- structured logging and distributed tracing (OpenTelemetry + Jaeger)
- containerized deployment (Docker + environment configuration)
Architecture
RustPulse follows a hexagonal architecture:
(handler → application → domain → adapter)
This allows:
- isolation of domain logic
- testable application services
- flexible infrastructure (DB, file fallback, etc.)
Flow
Agent → HTTP API → Application Service → Domain → Repository → Storage
System Design Focus
Reliability
- idempotent ingestion strategy
- fallback storage (JSONL) for degraded environments
- fail-fast configuration validation
Failure Handling
- database unavailable → fallback mechanism
- invalid data → rejected early at boundary
- system designed for partial failure scenarios
Observability
- structured logging via `tracing`
- distributed tracing via OpenTelemetry
- local debugging via Jaeger
Engineering Practices
RustPulse is developed using production-like workflows:
- PR-based development (even as a solo project)
- structured commits (`feat`, `fix`, `test`)
- CI validation on every change
- reproducible local environment
Development Timeline
Developed with a structured roadmap and tracked tasks
Current State
RustPulse currently includes:
- REST ingestion API
- CLI agent sending telemetry
- PostgreSQL persistence + fallback storage
- observability stack (tracing + Jaeger)
- CI/CD pipeline
- Docker-based local deployment
Next Steps
Current priorities (non-exhaustive):
- idempotency improvements
- authentication layer (JWT)
- retry and failure handling strategies
- backpressure and load shedding
Future work will be prioritized based on observed system constraints and real-world usage patterns.
Purpose
RustPulse is demonstrating how to build production-grade backend systems in Rust, with emphasis on:
- system reliability
- architecture design
- observability
- engineering
