13.3.3. Invalidation Mode and Shared Cache Loaders

When used in conjunction with a shared cache loader, JBoss Data Grid's invalidation mode causes remote caches to refer to the shared cache loader to retrieve modified data.
The benefits of using invalidation mode in conjunction with shared cache loaders include the following:
  • Compared to replication messages, which contain the updated data, invalidation messages are much smaller and result in reduced network traffic.
  • The remaining cluster caches look up modified data from the shared cache loader lazily and only when required to do so, resulting in further reduced network traffic.
