[jira] [Created] (OAK-3447) Parallelize recursive usage of compareAgainstBaseState

Joel Richard created OAK-3447:
---------------------------------

             Summary: Parallelize recursive usage of compareAgainstBaseState
                 Key: OAK-3447
                 URL: https://issues.apache.org/jira/browse/OAK-3447
             Project: Jackrabbit Oak
          Issue Type: Improvement
          Components: core
    Affects Versions: 1.3.6
         Environment: All, especially document
            Reporter: Joel Richard


In order to improve the performance of compareAgainstBaseState, it would help to parallelize the recursive usage of compareAgainstBaseState. The idea is that each sub tree which has a different revision would then be processed in parallel (although it would probably suffice to only fork the process when the nodes are not cached). This should significantly reduce the time which is lost while waiting for an external database assumed that there are at least two changes between the base revisions.
