Mete Atamel commented on OAK-535:
---------------------------------
Possibly and your comment highlighted another problem with the current
MoveNodeInstruction. In "copy existing nodes" part, it tries to fetch all
descendants of the moved node, /a/b, using FetchNodesAction but
FetchNodesAction will fetch /a/bb as well when it shouldn't.
> MergeCommand reads complete tree into memory

> Merging commits to a branch back to head in MongoMK calls MergeCommand, which
> reads the complete tree into memory. The more content is in the repository,
> the longer it takes to store even a simple update as a property change.
