Tomek Rękawek commented on OAK-3892:
------------------------------------
Good idea. Why don't we create a {{ReentrantLock}} directly?
> RDBDocumentStore: StripedNodeDocumentLocks - special case root?

> {{StripedNodeDocumentLocks}} currently handles all document IDs the same way.
> I assume that we see a lot of updates on {{0:/}}, though. These updates would
> be blocked if another different ID fell into the same lock stripe (and was
> being updated).
> We currently have 4096, so the likelihood isn't that big; on the other hand,
> a change doesn't seem to be risky.
