[jira] [Created] (OAK-4498) Lower limit for gc() maxRevisionAge

Marcel Reutegger created OAK-4498:
-------------------------------------

             Summary: Lower limit for gc() maxRevisionAge
                 Key: OAK-4498
                 URL: https://issues.apache.org/jira/browse/OAK-4498
             Project: Jackrabbit Oak
          Issue Type: Improvement
          Components: core, documentmk
            Reporter: Marcel Reutegger
            Assignee: Marcel Reutegger
            Priority: Minor
             Fix For: 1.6


Introduce and enforce a lower limit for maxRevisionAge in VersionGarbageCollector.gc().

OAK-4494 changes the way documents in a cache are considered up-to-date. In addition to the modCount value it also considers the modified timestamp. To work properly, a new document must have a modified timestamp that is different from a previous incarnation (i.e. before gc removed it). The version GC should therefore not remove documents with a maxRevisionAge less than the modified resolution (5 seconds).
