## What it is
A Go port of the LMAX Disruptor, a high-performance inter-thread/goroutine messaging library built on a pre-allocated ring buffer. It achieves hundreds of millions of messages per second between goroutines by avoiding locks and garbage collection pressure, far outperforming Go channels.

## Use cases
- pass messages between goroutines at maximum throughput
- replace slow Go channels in hot paths
- build low-latency event processing pipelines
- avoid GC pauses from message allocation
- fan out messages to consumer groups in sequence

## When to choose
- you need an order of magnitude more throughput than channels provide
- consistent, predictable message processing latency matters
- you can structure consumers as handler groups on a ring buffer

## When to avoid
- your message rates are modest and channels suffice
- you need network-distributed messaging rather than in-process
- you want a simple, familiar API over raw performance

## Facets
- artifact type: library
- maturity: active
- function: concurrency, message-queue
- domain: developer-tools, performance, microservices
- platform: go, cross-platform
- tags: lmax-disruptor, ring-buffer, high-throughput, lock-free, garbage-free, inter-goroutine-messaging
