Module: google.appengine.api.datastore_file_stub

In-memory persistent stub for the Python datastore API. Gets, queries,

and searches are implemented as in-memory scans over all entities.

Stores entities across sessions as pickled proto bufs in a single file. On startup, all entities are read from the file and loaded into memory. On every Put(), the file is wiped and all entities are written from scratch. Clients can also manually Read() and Write() the file themselves.
