Cloud Data Stream

Project Overview

Challenge

Traditional microservice communication patterns introduce significant latency overhead, especially in high-frequency trading and real-time analytics scenarios. HTTP-based REST APIs and standard messaging systems couldn't meet our sub-millisecond latency requirements for streaming workloads processing millions of events per second.

Solution

Cloud Data Stream (CDS) is a revolutionary communication platform built on RSocket TCP protocol, designed for ultra-low latency microservice communication. It combines reactive streaming with binary protocols to achieve sub-millisecond message delivery while maintaining high throughput and reliability.

Key Capabilities

Sub-millisecond Latency

P99 latency under 1ms with binary protocol optimization

Massive Scalability

1M+ concurrent connections with horizontal scaling

Fault Tolerance

Circuit breakers, retries, and graceful degradation

Real-time Analytics

Stream processing with Apache Flink integration
