Appengine - Writes Are Limited To 1 Per Second

I'm looking into using the AppEngine DataStore for a database system, but I'm confused by this quote in the documentation: 'This allows queries on a single guestbook to be strongly

Solution 1:

Hey, nope, having a reference to another entity and belonging to the same entity group as another entity are two independent things.

Entities belong to the same entity group only if you explicitly supply a parent argument when you instantiate either of them. Modeling an entity class so that it has a reference to another entity doesn't mean you're required to give it a parent when you construct it and therefore doesn't imply that it has to belong to an entity group with other entities.

The writes-per-second limit with High Replication applies to entity groups, so if you don't parent your entities to one another, each entity will be its own solo entity group. In that case, the writes-per-second limit will apply to each entity, not across entities.
