Bundle : Expiration

The expiration bundle serves a very simple purpose: it deletes the documents whose time has passed. Usage scenarios for the Expiration Bundle include storing user sessions in RavenDB or using RavenDB as a cache.

Usage

You can set the expiration date for a document using the following code:

DateTime expiry = DateTime.UtcNow.AddMinutes(5);
using (IDocumentSession session = store.OpenSession())
{
	session.Store(user);
	session.Advanced.GetMetadataFor(user)["Raven-Expiration-Date"] = new RavenJValue(expiry);
	session.SaveChanges();
}

As you can see, all we need to do is to set the Raven-Expiration-Date property in the metadata for the appropriate date, and, at the specified time, the document will be automatically deleted.

Note

The date must be UTC, not local time.

Warning

When master-master replication is set between servers, the Expiration bundle should be turned on ONLY on one server, otherwise conflicts will occur.
