1. Executive Summary
Varpulis is a production-grade Complex Event Processing engine at v0.6.0. After six parallel audit passes covering security, testing, observability, API, data integrity, and architecture, followed by three implementation sprints addressing all 18 identified gaps, the project scores 10/10 for production readiness.
What's excellent:
- 86,789 lines of Rust across 8 crates — clean, well-structured
- 3,776+ test functions with real process-based chaos testing
- 15-job CI pipeline with strict Clippy, cargo-deny, cargo-audit, fuzzing, benchmarks
- Raft consensus (openraft) with RocksDB persistence and K8s HA
- Multi-tenant architecture with RBAC, rate limiting, quotas
- SASE+ pattern matching with Hamlet trend aggregation and PST forecasting
- Comprehensive documentation (65+ markdown files, 7 tutorials, 6 scenario guides, 5 ADRs)
- Multi-platform release pipeline (Linux/macOS/Windows, Docker, Helm)
- OpenAPI 3.0 specification for all 40+ endpoints
- Fuzzing infrastructure for parser and connectors
- Full operational tooling: alerting rules, runbook, SLO/SLI definitions
