WHAT YOU’RE BUILDING

HeliosDB Phase 1: Enterprise-Grade Production Database

Current State: 40-60% complete (336,856 LOC across 168 crates) Target State: Fully production-ready, competitive database Timeline: 6-7 months (24-30 weeks) Investment: $506K engineering budget Team: 8-12 engineers across 5 work streams

Success Definition:

All 5 critical blockers resolved
TPC-C >5,000 tpmC (4x performance improvement)
SIMD 60%+ coverage (4x average speedup)
Enterprise monitoring & deployment guides
2,000+ tests passing, 100+ benchmarks met
Production-ready for enterprise customers

🔴 CRITICAL BLOCKERS TO FIX

Blocker	Status	Effort	Critical Path
1. SSI/Serializable	40%	11-15w	YES - BLOCKS ALL
2. Custom B-Tree	30%	8-11w	Performance critical
3. MVCC GC	75%	1w validation	Quick win
4. 2PC Testing	60%	9-12w	Reliability critical
5. Index Consistency	50%	7-10w	Correctness critical

Most Important Finding: SSI (Serializable Snapshot Isolation) is NOT implemented but claimed to be supported. This allows data corruption with concurrent writes. Must be completed by Week 15.

CRITICAL SUCCESS FACTORS

SSI Implementation - Most complex, on critical path
- Requires distributed systems expertise
- TPC-C testing starts Week 12 (early validation)
- Weekly code reviews with expert
Team Assembly - Must have 6+ engineers by Dec 8
- Especially need SSI expert
- Start recruiting TODAY
Build System - Compilation must be fixed this week
- Blocks all development
- Guide: COMPILATION_FIX_GUIDE.md
Infrastructure - CI/CD and benchmarking ready by Week 1
- Performance validation essential
- Chaos engineering for 2PC critical
Weekly Reviews - Every Friday 3 PM UTC
- Track progress against 5 streams
- Early risk identification
- Course corrections as needed

⚠ TOP RISKS & MITIGATIONS

Risk 1: SSI Takes Longer Than 15 Weeks

Impact: Entire project slips Mitigation:

Dedicate 3 senior engineers
Weekly code review with expert
Early TPC-C testing (Week 12, not Week 15)
Escalate to VP Engineering if slip >1 week

Risk 2: Can’t Hire 8-12 Engineers Fast Enough

Impact: Timeline extends, quality suffers Mitigation:

Start recruiting THIS WEEK
Consider contract engineers
Internal transfers from other teams
Accept phased onboarding

Risk 3: B-Tree Performance Doesn’t Hit 5K+ tpmC

Impact: Competitive disadvantage Mitigation:

Weekly benchmarking from Week 5
Lock contention analysis by Week 8
Fallback: Could ship with 3K tpmC (still acceptable)

Risk 4: Compilation Fix Takes Longer

Impact: Week 1 start delayed Mitigation:

Have Rust experts on standby
Fallback to reduced scope testing if needed
Worst case: Week 1 starts Day 2 instead of Week 1
