# 🗺️ Rust Logic Graph - Roadmap
**Slogan**: "Reasoning Engine for Distributed Backend & AI Orchestration"
Project roadmap focused on reasoning, distributed systems, and AI orchestration.
---
## 🎯 Vision & Direction
Rust Logic Graph is a **reasoning engine** for backend developers building intelligent distributed systems:
### Core Philosophy
- 🧠 **Reasoning over Automation** - Not just executing tasks, but making intelligent decisions
- 🌐 **Distributed-First** - Built for microservices, multi-database, multi-service architectures
- 🤖 **AI-Native** - LLMs and AI models as first-class citizens, not plugins
- ⚡ **Performance Matters** - Sub-millisecond latency, zero network overhead (embedded library)
- 🔧 **Developer-Centric** - Code-first, type-safe, testable workflows
### What We Build
1. **Distributed Reasoning Systems**
- Query multiple databases simultaneously
- Aggregate and correlate data across services
- Apply business rules to distributed data
- Make decisions based on global state
2. **AI Agent Orchestration**
- Multi-step LLM reasoning chains
- Tool calling and function execution
- RAG (Retrieval-Augmented Generation) pipelines
- Multi-agent collaboration systems
3. **Production Patterns**
- Saga pattern for distributed transactions
- Circuit breakers and fault tolerance
- Retry logic with exponential backoff
- Event-driven reasoning
### What We DON'T Build
- ❌ No-code workflow builders
- ❌ Batch ETL tools
- ❌ General-purpose automation
- ❌ Standalone SaaS platform

### v0.10.0 - Distributed Systems & Orchestration 🎯 NEXT

---
### ~~v0.11.0 - REST API~~ ❌ REMOVED
**Reason**: Conflicts with vision - Rust Logic Graph is an embedded library, not a standalone service like n8n. Users embed it in their own applications and build their own APIs if needed.
**Alternative**: Users can easily wrap the graph executor in Actix-web/Axum/Rocket for their specific needs.
---
### ~~v0.12.0 - GraphQL API~~ ❌ REMOVED
**Reason**: Same as above - focus on library embedding, not external API exposure. GraphQL belongs in user's application layer, not in the reasoning engine.

## 📝 Notes
### Decision Log
- ✅ Chose rust-rule-engine for GRL support (reasoning capabilities)
- ✅ Decided on Tokio for async runtime (performance)
- ✅ JSON/YAML for graph serialization (flexibility)
- ✅ Optional feature flags for integrations (modularity)
- ✅ **Library-first approach, not SaaS** (differentiator from n8n)
- ✅ **Focus on developers, not business users** (clear target audience)
- ✅ **Reasoning engine, not automation tool** (core positioning)
### Questions
- Q: Support YAML for graphs? ✅ Answered: Yes, added in v0.8.5
- Q: Build REST API? ❌ Decided: No, users build their own (embed-first)
- Q: Build GraphQL API? ❌ Decided: No, focus on library (not service)
- Q: Support visual workflow builder? ✅ Decided: Yes, but optional (v0.8.0)
- Q: Focus on distributed reasoning? ✅ Decided: Yes, core focus for v0.10+
### Strategic Direction
**What we ARE:**
- 🧠 Reasoning engine for distributed systems
- ⚡ High-performance orchestration library
- 🤖 AI agent coordination framework
- 🔧 Business rule engine with GRL
- 📦 Embeddable Rust library
**What we are NOT:**
- ❌ No-code automation platform (that's n8n)
- ❌ Standalone workflow service (we're embedded)
- ❌ Business user tool (we target developers)
- ❌ Replacement for Airflow/Prefect (different use case)
