--------------------------------
Fix Version/s: (was: 1.22.0)
> 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
> Components: core
> Reporter: Thomas Mueller
> Assignee: Thomas Mueller
> Priority: Major
>
> 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).
