LMAX-Exchange/disruptor

This system is a high-performance, low-latency inter-thread messaging library known as the Disruptor. It provides a ring buffer-based concurrency framework that enables efficient event processing through features like batch handling, multiple consumer topologies, and various wait strategies. The codebase includes extensive performance benchmarking and stress testing infrastructure to validate throughput, latency, and memory ordering under concurrent access.

The project migrated its build infrastructure to Gradle and updated the test suite to JUnit 5. This period also introduced batch processing capabilities and refactored the Disruptor DSL to improve extensibility and internal structure.

This period focused on expanding the Disruptor's performance testing coverage across various implementation patterns, including raw, sequenced, queue-based, and off-heap configurations. The work introduced new benchmark classes to measure throughput and latency for specific topologies and memory layouts, while also refactoring the test framework to report detailed batch processing metrics.

This period focused on enhancing the Disruptor library's usability and verifiability by introducing Java Platform Module System (JPMS) support and comprehensive JMH benchmarks. The team also expanded the codebase with extensive example code and stress tests to validate concurrency primitives and performance characteristics.
