i found in doc that if a field is set to null, its as like deleted the predicate from that object.
for example updated_at = null
if i were to sort a list of objects by updated_at, will it return records with updated_at set to null?
if it does not return those records, means i have to set it to something that means empty right?
if yes, what are the default values for null for all different data type of dgraph?
int = 0?
dateTime = ?
string = “” ?
float = 0.0 ?
bool = false ? no null?
