             Summary: RDBDocumentStore: StripedNodeDocumentLocks - special case root?
                 Key: OAK-3892
                 URL: https://issues.apache.org/jira/browse/OAK-3892
             Project: Jackrabbit Oak
          Issue Type: Technical task
          Components: rdbmk
            Reporter: Julian Reschke
            Assignee: Julian Reschke
            Priority: Minor


{{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.
