In plain English

This repository contains the Disruptor, a Java library designed for high-performance communication between threads within a single process. It is developed by LMAX Exchange and is intended for use cases where standard Java concurrency tools do not provide sufficient throughput or low enough latency. No readme is available in this repository.

Copy-paste prompts

Prompt 1

How do I integrate the Disruptor library into my Java project to replace a standard BlockingQueue for inter-thread communication?

Prompt 2

Show me a simple example of using Disruptor's RingBuffer to publish and consume events between two threads.

Prompt 3

What are the performance advantages of Disruptor over Java's built-in concurrent queues, and when should I use it?
