> Currently MongoDocmentStore creates a sparse index on {{_deletedOnce}}. As discussed [here|https://issues.apache.org/jira/browse/OAK-3070?focusedCommentId=15902888&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-15902888] it would better to create a partial Index [1].
> The criteria would be _modified, _deletedOnce : true
> This should only be done if Mongo >= 3.2
