问题 I've a use case where the stream should only emit when the cumulative "sum" equals or exceeds a given value, n. Let's take the example of six integers with n = 5. +---+------+---------+ | i | Emit | Sum | +---+------+---------+ | 1 | - | 1 | | 2 | - | 3 | | 3 | 5 | 1 | | 4 | 5 | 0 | | 5 | 5 | 0 | | 2 | 2 | 0 (end) | +---+------+---------+ As you can see, nothing is emitted unless the sum equals or exceeds 5, except for the last element, which is emitted anyway.

I tried with storing my observable in a variable,

But first lets answer small question what is Throttling? In software, a throttling process, or a throttling controller as it is sometimes called, is a process responsible for

问题 I am looking at some examples of reactive web applications and i am seeing them like this @RequestMapping(value = "/{id}", method = RequestMethod.GET) @ResponseBody public Mono<Person> findById(...) { return exampleService.findById(...); } @RequestMapping(method = RequestMethod.GET, produces = MediaType.TEXT_EVENT_STREAM_VALUE) @ResponseBody public Flux<Person> findAll() { Flux<Person> persons = exampleService.findAll(); return persons; } When i am reading about the Mono and Flux in the
