my main frustration with realm is that the design for the rxjava support is not that great. I can't use custom schedulers when fetching data and almost always end up mapping realm data objects to Pojo immutable entities generated with Autovalue, thus giving up the lazy loading speedup (since I have to copy all the data). also sometimes the asObservable() method returns empty collections a few times before returning the whole collection EVEN IF FILTERED WITH .isLoaded() and is wayyy too much spammy (it redelivers to subscribers a whole lot more times than when the underlying model is written to), therefore I have to debounce the stream with 1 second to save the adapter from rebinding the whole dataset again.
