Development of an UltraLow Latency In-Memory Message Broker Supporting Real-Time Tree Data Updates

The client requires a high-performance message broker capable of processing thousands of in-memory data structure updates per second. The system must deliver updates to relevant subscribers with sub-millisecond latency, ensuring sequential and reliable data delivery. Existing solutions faced limitations in throughput, latency, and efficient memory management, which hindered the scalability and responsiveness of their core services.

A large-scale, innovative technology firm specializing in real-time data processing and high-speed communication services for backend infrastructure.

• Develop a stable and scalable in-memory message broker capable of handling over 50,000 leaf structure updates per second.
• Ensure real-time delivery of message notifications to subscribers within less than 1 millisecond after receiving data updates.
• Implement sequential, ordered processing of data updates and notifications, supporting complex path subscriptions with wildcards.
• Optimize memory usage to minimize garbage collection impact and improve overall system performance.
• Design a simple, elegant, and highly usable API with a refined DSL for ease of integration and maintenance.
• Establish a robust CI/CD pipeline with comprehensive unit and integration testing to support reliable deployment and updates.

• High-throughput engine processing at minimum 50,000 leaf updates per second.
• Low latency delivery (<1 ms) of messages to all relevant subscribers immediately after data update.
• Sequential processing of data modifications and subscriber notifications to preserve input order.
• Support for complex subscription paths with wildcards for flexible data access.
• Optimized memory management to reduce garbage collection pauses and improve throughput.
• Refined domain-specific language (DSL) for simplified configuration and usage.
• Resilient architecture ensuring stability under high load conditions.

• External subscriber notification services with support for complex subscription paths.
• Monitoring and logging systems for performance metrics and health checks.
• CI/CD tools for continuous integration and deployment pipelines.

• Process over 50,000 leaf updates per second with stable performance.
• Deliver messages within less than 1 millisecond after update reception.
• Minimize garbage collection pauses through memory optimizations.
• Ensure high availability and fault tolerance under sustained high load.
• Maintain over 99.9% uptime and resilience during network fluctuations.

The new system aims to enable the client to handle high-volume, real-time data updates efficiently, significantly reducing message delivery latency to under 1 ms. This will improve the responsiveness and scalability of their core services, supporting growth in high-speed transaction processing, real-time analytics, and complex event handling, thereby strengthening their competitive position in the market.
