An AEM instance is updating and replicating pages at a very high rate. Monitoring alerts show a large number of requests to the publish instances.
How can the DevOps engineer throttle the number of cache invalidations?
The Dispatcher /gracePeriod setting throttles .stat file touching during frequent successive activations. It permits stale auto-invalidated content to be served briefly, preventing each replication from repeatedly invalidating the cache and increasing load on publish instances.
