Hi everyone!!
Please tell me. Can Rx execute parallel processing like awaitAll of Kotlin coroutine?
I think it is similar to "zip" but it can't use List<T>.
I'm waiting for messages. thanks.

The merge or flatMap operators are probably the closest to awaitAll.

Thank you:)

I'd say combineLatest().take(1)

zip is fine as well, just take 1 it

and subscribe each observable on "its own" io scheduler, then youll get parallelism

There is also parallel flowable, but without it you have flatmap, additionally with Max concurrency parameter
