[jira] [Created] (OAK-3329) TarMK cleanup blocks writers

Michael Dürig created OAK-3329:
----------------------------------

             Summary: TarMK cleanup blocks writers
                 Key: OAK-3329
                 URL: https://issues.apache.org/jira/browse/OAK-3329
             Project: Jackrabbit Oak
          Issue Type: Improvement
          Components: segmentmk
            Reporter: Michael Dürig


TarMK cleanup exclusively locks the {{FileStore}}, which causes concurrent writers to block until cleanup finished. Initially cleanup was expected to be reasonably fast, however I have seen it taking dozens of minutes under certain circumstances (most likely many tar files with many small segments, aka OAK-2896).
