About:
ConcurrentQueue is a C++11 header-only library providing a highly efficient, lock-free concurrent queue. It is designed for high-performance scenarios, offering low-latency operations with minimal overhead. The library supports both single-producer/single-consumer and multi-producer/multi-consumer patterns.

Key Features:

Header-only library (no compilation required)
Lock-free and wait-free operations for high throughput
Supports multiple producers and consumers
Memory-efficient with dynamic sizing options

Use Cases:

Real-time data processing pipelines
High-frequency trading systems
Multithreaded game engines
Asynchronous task scheduling

Alternatives:

boost::lockfree::queue – Boost provides similar functionality but requires linking against the larger Boost libraries, whereas ConcurrentQueue is a lightweight, single-header solution.
folly::MPMCQueue – Facebook's Folly library offers robust queue implementations but has a heavier dependency footprint compared to the standalone ConcurrentQueue.
