Reduction of Update Propagation Delay

  • We agreed to apply shorter TTLs for .cvmfspublish and catalogs
  • Existing repositories can be migrated (if CVMFS_SERVER_TTL is not set)
  • Clients should use a jitter for the checking interval for new catalogs
  • Dave agreed to check if 30s .cvmfspublish TTL is harmful with Squid servers

Cache plugin status

  • In-memory part of the software
  • RAMCloud should move into the contrib repository
  • Chirp: Tim?
  • NDN under development
  • Hadoop under development
  • XRootD: Planned as a CERN summer student project
  • Ceph/librados, POSIX (external): interesting, no developer yet

 YubiKey Support

  • Might require physical test hardware (e.g. VBox on Mac host)
There are minutes attached to this event. Show them.

      Reduction of Propagation Delay 20m

      Suggestion to adjust default TTLs to

      • 30s for .cvmfspublished
      • 4min for file catalogs
