[Community] disruptor-cpp: Complete 1:1 C++ port with all tests and real-world exchange example

[justinzhuguangwen]

Hi LMAX team,

I've created a complete 1:1 C++ port of the Disruptor pattern:

Repository: https://github.com/SkynetNext/disruptor-cpp

What's Included

• Complete API port: All core components under include/disruptor/**

  • RingBuffer, Sequencer, WaitStrategy, BatchEventProcessor, etc.
  • Namespaces: disruptor, disruptor::dsl, disruptor::util

• All Java tests migrated: Ported to GoogleTest under tests/disruptor/**

• JMH-aligned benchmarks: C++ benchmarks under benchmarks/jmh/** using Google Benchmark

  • SingleProducerSingleConsumer
  • MultiProducerSingleConsumer
  • BlockingQueueBenchmark
  • Directly comparable to Java JMH results

Real-World Usage

Used in exchange-cpp, a high-performance matching engine (C++ port of exchange-core):

• Sub-microsecond order processing latency
• Same multi-stage pipeline architecture (R1 → ME → R2 → E)

Benchmark Comparison

The project includes scripts to run both Java JMH and C++ benchmarks side-by-side for fair comparison. See docs/BENCHMARK_RESULTS.md.

Would you consider adding a link to this project in your README under community ports or related projects?

Happy to discuss any technical details.
