Request : LiveData observing Query.count instead of Query.find

Hi,

I'd like to use LiveData to observe the number of items resulting of a given query (the equivalent of Query.count() or Query.findLazy().size()).

As of v2.4.0, LiveData only calls Query.find, so the only implementation I came up with is not optimal at all

// Get all results as objects
// NB : db.queryContentSearch is a Query<Content>
ObjectBoxLiveData<Content> livedata = new ObjectBoxLiveData<>(db.queryContentSearch(query, metadata, favouritesOnly));

// Instanciated objects are useless because we just actually count them !
MediatorLiveData<Integer> result = new MediatorLiveData<>();
result.addSource(livedata, v -> result.setValue(v.size()));
return result;

=> Would it be possible in future versions to build LiveData's that observe Query.count ?
Or have I overlooked a feature that already exists ?

Thanks a lot for your help,

Comienza revisando el comportamiento actual de LiveData que llama a Query.find y, después, compara las APIs Query.count y Query.findLazy descritas en el issue. Se considera terminado cuando una opción de LiveData puede observar el recuento de una query sin materializar todos los objetos de resultado y se actualiza cuando cambian los resultados de la query.
