The disruptor wizard is a simple DSL to make setting up the LMAX Disruptor simpler. The LMAX disruptor itself is an extremely high performance, low latency method of passing data between producers and consumers in a lock-free manner. It was developed by LMAX as part of their financial trading platform.
A simple consumer chain where A must process events before B which must be before C which in turn must be before D.
DisruptorWizard dw = new DisruptorWizard(ENTRY_FACTORY, ringBufferSize, executor);
dw.consumeWith(A).then(B).then(C).then(D);
A diamond shape dependency where A and B process any event. C depends on A, D depends on B and E depends on all previous tasks.
dw.consumeWith(A, B);
dw.after(A).consumeWith(C);
dw.after(B).consumeWIth(D);
dw.after(C, D).consumeWith(E);
