Google App Engine Unapplied Writes FAQ - Google App Engine - Google Code

What is an unapplied write?

Unapplied writes are writes to the App Engine Datastore that did not get replicated from the primary to the secondary Datastore. Unapplied writes do not impact the transactional consistency and have not corrupted application data. You can think of them as causing the mirror image between the primary and secondary Datastore to be out of sync.
