Question

In the GAE documentation, it states:

Remember, if you do a get(), put(), or a transaction, you will always see the most recently written data.

I understand that db.get(key) always returns the most recently written data, but what about other gets? If I have an entity Voters and do this:

voter = Voters.order("email").get()

will I always see the most recently written data?

I’m pretty sure the answer is no, but it would be good if the docs were more explicit.

Answer 1

“queries that require strongly consistent results must contain an
ancestor filter, which restricts the results to a single entity group.
Queries that span multiple entity groups are not guaranteed to
return up-to-date results. See the Using the High Replication
Datastore for more information about using ancestor queries in this
context.”
