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
