Yes, it is called session and the key is the object id. One big
advantage of the session compared to a custom cache is that it is
integrated with the database operations (e.g., persist(), load(),
erase(), etc). So, for example, if you call load() and the object
is already in the session, then it will be automatically returned
without any database access.

For more information, see Chapter 10, "Session" in the ODB manual.
