Take collection / container offline
It would be useful to be able to take a collection / container 'offline'. For example, if we wish to delete a large collection, our policy is to make it inaccessible for 6 months prior to deletion.
Whilst we can do this at the client level, it would bring greater assurance a given collection is unused at the point of deletion if it had been offline for a few months beforehand.
Adjusting this from unplanned (backlog) to declined.
For scenarios where you want to ensure no requests are accessing a container you can use diagnostic logs for data plane requests to monitor these then query those over some period of time to ensure they are no longer being used before deleting.
