do namespaces separate entity groups?
lets say i have an app with multiple namespaces and each namespace has 1 entity group and the entity group key is not a real entity but a key construction like.
master_group = ndb.Key('Foo', 'bar')
if all namespaces have the same entity group key does it count as 1 single entity group OR is it separated by the namespace which is included in the Key object and there are as many master_groups as namespaces ?
The docs state that the current namespace is applied to a Key when it is created. Keys take a namespace argument. Thus, root entities in different namespaces are in different entity groups.
