> The fix for OAK-1056 introduced a regression which causes preliminary creation of the persisted branch instead of keeping changes in memory up to a certain size. 
> The problem is that transient changes are [purged|https://github.com/apache/jackrabbit-oak/blob/1e4eb5f15d36922c8e6eaa8ff1316e5f512f4352/oak-core/src/main/java/org/apache/jackrabbit/oak/plugins/document/DocumentRootBuilder.java#L107] with every call to {{NodeBuilder.getNodeState}}. That purge is what ultimately leads to the persisted branch being created.
