What occurs when a non-persistable entity is committed?

When a non-persistable entity is committed, the current attribute values and association values are stored in memory. This means that while the entity exists and can be manipulated within the app's runtime, it does not get saved to the database. Non-persistable entities are typically used for transient data or for calculations that do not need to be stored permanently. When the transaction concludes, the non-persistable changes are not retained beyond the session unless explicitly managed by the application logic.

The other options incorrectly suggest various states that a non-persistable entity might undergo upon committing. For instance, saving data permanently to the database does not apply here, as non-persistable denotes temporary rather than permanent storage. Likewise, resetting attributes to default values or only retaining primary key values does not align with the behavior of non-persistable entities since they maintain current states in memory as long as the app is running.
