Hello
I’ve been google for some time now and SO and couldn’t really find a reason for this:

I have Room returning Flowable<List<Model>> — This Model is a data class (hence I would assume equals() works as expected). But for some reason I get multiple notifications on a db change (I’ve mapped it with distinctUntilChanged())

This question [1] is addressing the same but I’ve had no success with the suggestions, and the accepted answer is referencing exactly Object.equals, I’ve also tried [2] using the suggestion as the distinct predicate, but with no success

Thank you in advance for your time

Does it have a primitive array? If so, you need a custom equals and hashCode that uses contentEquals and contentHashCode on those properties for value equivalence to work.
