Config changes invalidating cache

With the model, a high number of sessions can concurrently access the same entity without hitting the database each time; hence the performance gain.

Several cache providers have been contributed by NHibernate users: , uses ASP. This provider also supports SQL dependency-based expiration, meaning that it is possible to configure certain cache regions to automatically expire when the relevant data in the database changes.

Command-based dependencies work only with SQL Server 2005.

NHibernate provides a cache instances of the object type being cached; instead it caches the individual values of the properties of that object. One, NHibernate doesn't have to worry that your client code will manipulate the objects in a way that will disrupt the cache.Because when it comes to knowing the state of the data and when to invalidate, the server knows best, I believe the caching is the responsability of the server and should be taken care of by the server.But sometimes you do not have control over the caching headers, for example when using a third party API.Some pages even made multiple calls to the same endpoint at the same page.Luckily in most cases we have control over the configuration of the server as well, so if we properly configure the caching headers, everything is fine.

With table-based notifications, the application will poll the database for changes at a predefined interval.
