Hot  vs Cold observables – From the RxJs wiki [github.com]

  • uses js instead of java, but concepts are the same and this is the best explanation I’ve found so far.

RxJava wiki on Backpressure [github.com]:

  • Ring buffer size: `System.setProperty(“rx.ring-buffer.size”, “128”);`
  • Issue with changing buffer ring size [github.com]
  • It’s 16 on Android, down from 1024 originally. :P So it’s actually 64x smaller.
