XAP provides advanced persistency capabilities for the Space architecture.
XAP persistency overview.
Direct persistency mode support Read-Write Through
The default Hibernate implementation of the Space Persistency APIs.
Space Data Source API
The space Data Source API is used for reading data and meta data from the data source.
Space Synchronization Endpoint API
The space synchronization endpoint API is used for synchronizing data from the space to an external application or a data base.
Space data source initial Load pre-loads the space with data before it is available for clients.
Reliable Asynchronous Persistency (Mirror)
How to specify that some objects in a persistent space should not be saved to the persistent storage.
Space Persistency advanced topics such as advanced operations, tuning, troubleshooting, and limitations.
XAP’s persistency approach consists of several paradigms for data persistency, according to the application needs. This section gives a basic overview of each paradigm.
Migrating External Data Source
This page describes how EDS implementations prior to XAP version 9.5 should migrate to the new Space Persistency APIs.
