[jira] [Created] (OAK-4081) Faster cost calculation for property indexes and traversal

Thomas Mueller created OAK-4081:
-----------------------------------

             Summary: Faster cost calculation for property indexes and traversal
                 Key: OAK-4081
                 URL: https://issues.apache.org/jira/browse/OAK-4081
             Project: Jackrabbit Oak
          Issue Type: Bug
            Reporter: Thomas Mueller
            Assignee: Thomas Mueller


There are sometimes many property indexes, therefore cost calculation is slow. As seen in OAK-4076, we could re-order the indexes and stop once we found a good one (specially for unique indexes).

Also, currently we still check if traversal is faster than using an index. In many cases this check is not needed.
