LMAX-Exchange/disruptor

This is the Disruptor library, a high-performance, lock-free, thread-safe data structure for inter-thread communication. It provides a ring buffer and a DSL-style API to define event processing pipelines, supporting single and multi-producer/consumer topologies with features like batch processing and exception handling. The codebase includes extensive performance benchmarks and stress tests to validate concurrency primitives and throughput across various configurations.

The project underwent a significant modernization by migrating to a Gradle build system and upgrading to JUnit 5, while simultaneously introducing new features for batch event processing and a DSL-style configuration API. This period focused on improving throughput capabilities and test coverage, supported by updated dependencies and performance benchmarking utilities.

12 changes

The period focused on expanding and standardizing the Disruptor's performance test suite. New tests were added to cover raw, sequenced, queue-based, and off-heap scenarios, while the test infrastructure was refactored to support batch metrics and improved reporting.

7 changes

This period focused on enhancing the Disruptor library's testability and usability by introducing JMH benchmarks for performance analysis and JCStress tests for concurrency correctness. Additionally, the codebase was expanded with comprehensive example code and a Java module descriptor to support modern development practices.
