Cache integration overview
The crucial element that gives WebSphere eXtreme Scale the capability to perform with such versatility and reliability is its application of caching concepts to optimize the persistence and recollection of data in virtually any deployment environment.
- JPA Loaders
The Java Persistence API (JPA) is a specification that allows mapping Java objects to relational databases. JPA contains a full object-relational mapping (ORM) specification using Java language metadata annotations, XML descriptors, or both to define the mapping between Java objects and a relational database. A number of open-source and commercial implementations are available.
- JPA cache plug-in
WebSphere eXtreme Scale includes level 2 (L2) cache plug-ins for both OpenJPA and Hibernate Java Persistence API (JPA) providers.
- HTTP session management
The session replication manager that is shipped with WebSphere eXtreme Scale can work with the default session manager in the application server to replicate session data from one process to another process to support user session data high availability.
- Listener-based session replication manager
The eXtreme Scale session replication manager that is shipped with WebSphere eXtreme Scale can work with the default session manager in the application server to replicate session data from one process to another process to support user session data high availability.
- Dynamic cache provider
The Dynamic Cache API is available to Java EE applications that are deployed in WAS. The dynamic cache provider can be leveraged to cache business data, generated HTML, or to synchronize the cached data in the cell by using the data replication service (DRS).
