Preloading Options

Preloading refers to the loading of the cache with objects from the backing store, at system startup.

If you do not preload, then the objects are loaded as needed, which can affect performance the first time each object is requested, depending on the size of the objects.

At the default level, you can choose to preload or not preload two types of items separately: the objects themselves, and the handles to the objects, which are stored in a separate table called the object table. You can also specify the number of objects to preload (one setting for both types of items).

At the individual object level, you can override the preload setting as follows:

  • Use the default setting
  • Preload (True)
  • Do not preload (False)

You can also specify (or override) how many objects to preload.

Note: One tuning property for preloading is available: be.engine.cluster.recovery.threads
