Realm is a mobile database: an alternative to SQLite and key-value stores

SQLBrite adds reactivity to SQLite (https://github.com/square/sqlbrite)

But in general I rely on RxJava to provide fine grained notifications. For example (psudeocode):

    someUserQueryThatReturnsObservable()
      .map(user->user.firstName)
      .distinct()
      .subscribe(newFirstName->newFirstName)

It's messy because you end up having to repeat everything after map for every property, not really an ideal solution

I started using sqlbrite (in combination with sqldelight) and stopped treating the database as an object store. Instead I create an interface for the data the customer needs (e.g. an item interface for elements in a listview), write a select query whose result fulfills this interface, and let the rest happen via databinding. This seems to work fine up to a couple of thousand of elements for me.
