1. In the [Usage Notes](https://developers.google.com/appengine/docs/python/datastore/hr/overview) for the High Replication Datastore, it says that an entity group is limited to 1 write per second. I'm a little confused on that. In the [Understanding Write Costs](https://developers.google.com/appengine/docs/python/datastore/entities) section of this other article, it shows that just storing a new entity can cost 14 writes. Is the 1 write per second mentioned in the first article an equivalent measure to the one in the second article? If so, it would take 10 seconds to store a basic entity? I'm sure that can't be correct?
2. Google says that entities stored without ancestors (as root entities) have eventual consistency. Does this mean that if one user adds a new entity to the datastore without an ancestor, that it is not guaranteed to be available if I do a query immediately after? If so, how long is "eventual" anyway? Can it be hours, or are they just talking seconds?
