             Summary: Investigate changing the UUID generation algorithm / format to reduce index size, improve speed
                 Key: OAK-7374
                 URL: https://issues.apache.org/jira/browse/OAK-7374
             Project: Jackrabbit Oak
          Issue Type: Improvement
            Reporter: Thomas Mueller
            Assignee: Thomas Mueller
             Fix For: 1.10


UUIDs are currently randomly generated, which is bad for indexing; specially read and writes access, due to low locality.

If we could add a time component, I think the index churn (amount of writes) would shrink, and lookup would be faster.

It should be fairly easy to verify if that's really true (create a proof-of-concept, and measure).
