>
> The DocumentStore API allows for conditional inserts (only add document if
> not present yet) and updates (using findAndModify() with a condition), but it
> doesn't allow you to remove a document given some conditions are met.
> This feature is required to make sure the VersionGarbageCollector does not
> remove document that are modified concurrently. See OAK-2778.
