Hi, this is currently not possible because the DocumentStore API does not have such a method. There's an existing issue closely related to your request:
https://issues.apache.org/jira/browse/OAK-2066 I think in general it makes sense to add such a method. As you can see in the issue, the background write is not the only application that would benefit from it.
