9.4. Synchronous/Asynchronous Invalidation
In Red Hat JBoss Data Grid's Library mode, invalidation operates either asynchronously or synchronously.
- Synchronous invalidation blocks the thread until all caches in the cluster have received invalidation messages and evicted the obsolete data.
- Asynchronous invalidation operates in a fire-and-forget mode that allows invalidation messages to be broadcast without blocking a thread to wait for responses.
