RxJava框架是无锁且无等待的吗？

Question

I am interested to know if RxJava framework is lock-free and wait-free like Lmax Disruptor? Does it use techniques like cache line padding to avoid false sharing for better performance?

Answer 1

It does use padding to minimize false sharing, but it definitely uses queues (home grown) and locks, countdownlatch in some places like .merge/.flatmap etc...

I don't think any decent framework would dare use busy-wait spinning under the hood without telling it's user base. It would be excruciatingly expensive on CPU.
