The LMAX Disruptor is an open-source library for high-performance concurrent programming, originally developed by the British financial company LMAX. It is based on the principles of lock-free concurrent programming and aims to provide an efficient way to handle data flow in event-driven systems.

In Apache Storm, the LMAX Disruptor is utilized as the default event processing engine for passing and handling data within the topology. By leveraging a ring buffer and multi-threaded concurrency, it achieves high-performance event processing, allowing Storm to efficiently handle large-scale real-time data streams. The design principles of the Disruptor include optimizing cache usage, reducing memory allocation, and minimizing the use of locks to enhance the efficiency and performance of the system.
