Reactive Stock Market Introduction This project takes you through the design of simple reactive stock market application. Sole purpose of this project is to educate. Takeaways: - Spring Boot application with matching engine as it core - Matching engine supports limit order - Matching engine is implemented using Max-Heap and Min-Heap - Lightweight and custom-built Reactive CQRS framework - Lockless - light thread synchronisation and good scalability potential - In-memory storage only - Supports backpressure and event streaming Anatomy - Matching engine + Matching Engine uses Max-Heap and Min-Heap + Time complexity for critical operations are as: + Add – O(log N) + Cancel – O(1) + Buy tree - The collection of orders sorted in the ascending order, that is, higher buy prices have priority to be matched over lower + Sell tree - The collection of orders in the descending order, that is, lower sell prices have priority to be matched over higher + Each state transition is the consequence of an event. Events are played sequentially and therefore engine is single-threaded - Reactive + Asynchro
