We're excited to announce all.source, a high-performance event store built in Rust, designed for event sourcing, CQRS, and AI-native workflows.
The Problem with Traditional Databases
In today's data-driven world, developers face critical challenges:
- State Amnesia: Traditional databases only store current state. When something breaks, you can't see how you got there.
- Temporal Blindness: Want to know what your data looked like last Tuesday at 3pm? Good luck.
- AI Integration Gap: Your data is trapped behind rigid APIs that weren't designed for autonomous workflows.
all.source tackles these challenges head-on with an event store that thinks.
What Makes all.source Different
1. Blazing Fast Performance
- 469K events/second ingestion throughput
- 11.9μs p99 query latency
- ~129MB binary footprint
Built in Rust with lock-free data structures and Parquet-based storage for both high-throughput ingestion and fast analytical queries.
2. Time-Travel Queries
Reconstruct any entity's state at any point in time:
# Get user state as of last Tuesday
GET /api/v1/entities/user-123/state?as_of=2026-02-04T15:00:00ZDebug issues, audit changes, or replay historical states instantly.
3. AI-Native by Design
27 MCP (Model Context Protocol) tools for seamless integration with Claude, GPT, and custom AI agents:
- Query events with natural language
- Create projections autonomously
- Manage schemas and pipelines
- Run analytics and correlations
Let AI agents manage your event streams.
Core Capabilities
| Feature | Description |
|---|---|
| Event Sourcing | Immutable event logs with full audit trail |
| Projections | 5 types including snapshots, counters, and funnels |
| Schema Registry | Versioned schemas with evolution and compatibility |
| Stream Processing | Filter, map, reduce, window operators |
| Multi-tenancy | Full isolation with RBAC and quotas |
