These are chat archives for ReactiveX/RxJava
RxJava – Reactive Extensions for the JVM – a library for composing asynchronous and event-based programs using observable sequences for the Java VM.
Is it a bug in rx2? Btw I obeyed your advice and I replace part
stringFlowable.concatMap(s -> Flowable.just(s) .delay(100, TimeUnit.MILLISECONDS)));
stringFlowable.compose(FlowableTransformers.spanout(10, 10, TimeUnit.MILLISECONDS, scheduler))
now it's working :)
