Marcel Reutegger commented on OAK-2151:
---------------------------------------
The root cause for this issue is the snapshot isolation (SI) implemented by
DocumentNodeStore. SI does not guarantee serializability of schedules. The
write skew anomaly occurs because adding a node in Oak usually does not modify
the parent. A conflict goes undetected if the parent is concurrently removed.
> DocumentNodeStore does not detect hierarchy conflict
