Betting Exchange

If you’ve ever wondered how a betting exchange works and how to build a simplified version of one, this blog series will help you achieve that:

• Part 1 — Motivation & System Architecture
• Part 2 — Inside the Order Matching Engine
• Part 3 — Inside the Order Book
• Part 4 — Inside the Event Streaming Pipeline
• Part 5 — Inside the Consumer Pipeline

The series is a mixture of system diagrams, prose, and code. By the time you’ve gone through it, you should be able to have a functioning system that can:

• ingest order-related events
• match them according to a matching policy
• emit trade events to an event log
• push trade events from the event log to downstram consumer services (analytics, persistence, etc.)
