Implementation Plan

What is Axiom? Axiom is an event ingestion and processing platform. I made this project to gain atomic understanding in making a production-grade system that ingests millions of events per day, processes them in real time, stores them durably, and exposes low-latency APIs while remaining secure, observable, fault-tolerant, and evolvable.

Think of it as a hybrid of:

• Kafka + Stripe webhooks
• Analytics ingestion (like Segment)
• Real-time notification pipelines

Repository

Axiom is seperated into 6 repo right now

1. axiom-ingest-gateway (go): Used to accept untrusted traffic at massive scale
2. axiom-log-engine (rust): Used for durable, replicated, append-only event storage
3. axiom-stream-processor (rusts): Used for deterministic, fault tolerant event processing
4. axiom-query-api (go): Read-optimized, low-latency access layer
5. axiom-control-plane (go): Config, schema, auth, and system governance
6. axiom-infra (terraform + k8s): Infrastructure as code and deployment strategy
