Caching

The EclipseLink cache is an in-memory repository that stores recently read or written objects based on class and primary key values. EclipseLink uses the cache to do the following:

• Improve performance by holding recently read or written objects and accessing them in-memory to minimize database access.
• Manage locking and isolation level.
• Manage object identity.
