[jira] [Created] (OAK-4553) Retain journal entries for valid checkpoints

Marcel Reutegger created OAK-4553:
-------------------------------------

             Summary: Retain journal entries for valid checkpoints
                 Key: OAK-4553
                 URL: https://issues.apache.org/jira/browse/OAK-4553
             Project: Jackrabbit Oak
          Issue Type: Improvement
          Components: core, documentmk
            Reporter: Marcel Reutegger
            Assignee: Marcel Reutegger
            Priority: Minor
             Fix For: 1.6


OAK-4528 will use the journal to answer diff calls. While the default max age for the journal GC is 6 hours, it may still happen that journal entries are deleted when they are actually still needed. E.g. consider a repository with async index update configured and the repository is shutdown with a valid checkpoint for the current async index state. If the repository is stopped for more than 6 hours, the journal GC may rather quickly remove all entries even though the async index update still needs some of them.
