Processing Engines in C++: Building Scalable, -Latency

When milliseconds cost millions, industries do not rely on garbage-collected languages; they rely on bare-metal C++ execution. Stream processing technology—powered by edge-triggered networking, lock-free queues, and zero-copy serialization—allows systems to ingest, route, and calculate millions of live events per second. It is the invisible force behind high-frequency trading platforms, real-time fraud detection, and global telecommunications infrastructure.Stream Processing Engines in C++ is a definitive, hands-on guide that takes you from a blank text file to a highly scalable, fault-tolerant distributed data architecture. Instead of relying on bloated, pre-packaged frameworks, you will build a custom engine from the ground up. You will master core-pinned thread schedulers, wait-free ring buffers, epoch-based memory reclamation, and distributed checkpoints. What's insideHigh-Performance Execution: Build custom thread pools and C++20 coroutine schedulers mapped directly to physical CPU cores.Zero-Copy Pipelines: Eliminate garbage collection pauses using custom slab allocators and binary schemas.Lock-Free Infrastructure: Replace slow mutexes with wait-free Single-Producer Single-Consumer (SPSC) and MPMC queues.The Network Perimeter: Bypass blocking sockets using edge-triggered epoll loops and strict flow control.Temporal Mathematics: Master Event Time, Tumbling Windows, and Late Triggers to calculate flawless real-time analytics.Distributed Fault Tolerance: Scale horizontally using Consistent Hash Rings and survive total cluster failure with Log-Based Replay. Who it's meant for This book is written exclusively for systems programmers, backend software engineers, and infrastructure architects who are tired of hiding behind slow abstractions. If you want to strip away the operating system interference, command the silicon directly, and learn how enterprise-scale platforms actually function under the hood, this guide is for you.
