16.3.3. The Cache Loader and Cache Passivation

In Red Hat JBoss Data Grid, a cache loader can be used to enforce the passivation of entries and to activate eviction in a cache. Whether passivation mode or activation mode are used, the configured cache loader both reads from and writes to the data store.

When passivation is disabled in JBoss Data Grid, after the modification, addition or removal of an element is carried out the cache loader steps in to persist the changes in the store.
