All, I am building an application where I need to model a 1-many relationship. The "many" side of the relationship needs to scale to about 1 million items at maximum. In his talk, Building Scalable and Complex Apps, Brett Slatkin suggests using ListProperty to model this type of relationship; however, ListProperty imposes a limit of 5000 indexed properties --- a far cry from the million I need (and, unfortunately, these items must be indexed so that I can find "one" side of the relationship by querying the "many" side).
So, I have a few questions: 1. If I could make it so that the many side of the relationship did not need indexing, can a ListProperty deal with 1 million (non- indexed) items? 2. If I require indexing on the many side, is there another approach that will work? My only other design alternative, I think, is to use a link entity (a -> link entity -> b). This allows me to use ReferenceProperty and it associated collection set. Thoughts? Am I missing something?
