## What it is
LMAX Disruptor is a high-performance, lock-free inter-thread messaging library for the JVM built around a ring buffer with 'mechanical sympathy' for hardware. It provides extremely low-latency, high-throughput message passing between threads.

## Use cases
- pass messages between threads with minimal latency
- replace blocking queues in high-throughput pipelines
- build low-latency trading or event processing systems
- implement producer-consumer pipelines in Java
- reduce lock contention in concurrent applications

## When to choose
- you need very low latency and high throughput for inter-thread communication on the JVM
- your bottleneck is queue-based message passing between processing stages
- you can restructure your pipeline around the ring buffer pattern

## When to avoid
- you need simple distributed or cross-process messaging
- your workload is low-volume and standard queues suffice
- you cannot adapt your architecture to the disruptor pattern

## Facets
- artifact type: library
- maturity: stable
- function: concurrency, message-queue
- domain: developer-tools, performance
- platform: jvm
- tags: ring-buffer, lock-free, low-latency, inter-thread-messaging
