UpdateBefore,
UpdateAfter,
NoUpdate,
}
Expand description
Changes how the view’s outdated data will be treated.
Variants§
UpdateBefore
Update any changed documents before returning a response.
UpdateAfter
Return the results, which may be out-of-date, and start an update job in the background. This pattern is useful when you want to ensure you provide consistent response times while ensuring the database is updating in the background.
NoUpdate
Returns the results, which may be out-of-date, and do not start any
background jobs. This mode is useful if you’re using a view as a cache
and have a background process that is responsible for controlling when
data is refreshed and updated. While the default UpdateBefore
shouldn’t have much overhead, this option removes all overhead related
to view updating from the query.
