Event Polling

The event polling mechanism in CIS is related to the Command Cache, in that it polls the content server on a scheduled interval and if changes are found, it sends out events through the CIS layer. These events tell the Command Cache that content has been updated, a subject has changed, etc., and to clear the cache appropriately. If the event poller is not enabled (via the Event Polling Properties tab on the adapter configuration page), then no events will be generated and the cached items will only be expired via their timeout values.

The EventPoller looks for two types of events:

Subject events are indications by the content server that something has changed under a given subject. These subjects are items such as documents, users, subscriptions, etc. Any of these subjects can be used to dirty an item in the command cache.
