TIBCO BusinessEvents Studio Project

Except for excluding entities from the backing store, modifying of the FraudDetectionCache project to support a backing store can be configured before or after setting up the backing store, and can be changed after the backing store is in place.

Can I exclude entities from the backing store?
 Yes. You can configure various settings at the individual entity type level. To exclude entities, use the CDD Cluster tab > Object Management > Domain Objects > Overrides feature. Clear an entity override’s Has Backing Store checkbox to exclude it from the backing store. See "Excluding Entities from the Backing Store" in TIBCO BusinessEvents Developer’s Guide for more details (including another way to exclude entities, using their Mode setting).
Note: If later you want to include any excluded entities, you must change the setting and update the backing store setup as explained in "Updating an Existing Backing Store Schema" in TIBCO BusinessEvents Developer’s Guide
What is preloading?
 When you use a backing store, you can preload entity data from the backing store to the cache before the system begins processing events. If you do not preload entities, they are fetched from the backing store as required at runtime (which means the first time objects are fetched is slower).
Why preload handles?
 Entity object handles are stored in a special cache that can be preloaded or not depending on storage and performance needs. It might be more efficient in some cases to preload handles and not objects, for example. See The Role of the Object Table in TIBCO BusinessEvents Architect’s Guide for more details.

Preloading commonly used objects can improve performance after startup. By default, no preloading is done. You can preload all objects or objects of selected entity types, as desired. See Domain Objects Configuration in TIBCO BusinessEvents Developer’s Guide for the procedure.
