      Description

      The current collision handling on conflict in the DocumentNodeStore can be rather expensive when there are old branch commits which were not merged.

      A commit that includes documents with old branch commits that have not been merged will always attempt to set a collision marker on the commit root document for those changes.

      While it is difficult to tell whether a branch commit will be merged at some point, at least those branch commits that were created before the most recent startup of a cluster node cannot be merged. The collision handling logic could be improved to take the start time of a cluster node into account.
