Agenda

  • Storage
    • high-level aggregated Capacity information
    • agreement on Share definition!
    • Collection of use cases for datastore entity
    • AOB

Participants

  • Sergio Andreozzi (CNAF)
  • Felix Ehm (CERN)
  • Maarten Litmaath (CERN)
  • Stephen Burke (RAL)

Minutes

Actions:

  • Maarten to provide definition for accessLat/RetPol/ExpMode values to be added in 18.33/34/35

Open issues

  • where to get summary size info
    • think of a summary class to be related to the storageService
  • space can be free/used/reserved
    • reserved is a state that applies to SRM implementations

  • how to discover types of AccessLatency/RetentionPolicy
  • why ExpirationMode is multi-value?
    • because they are the possible supported by the SRM implementation
    • expirationMode values are taken from SRM v.3
    • when putting a file, a user can specify which expirationMode to assign to a file
  • What about an ExpirationMode default value?
    • SRM states "volatile"
    • we do not feel the need to publish the default
  • do we need a maximumLifeTime/defaultLifeTime?
    • ADDED
  • Maarten: RetentionPolicy, why not multi-value?
    • Agree that can be multi-value

current SRM does not support it, but in the future, it can be that a share can support e.g., both custodial and replica

  • Why Tag multi-value?
    • added a comment, to verify later
  • still to discuss what to privilege in the design
    • unnormalized-> implies redundancy, but simpler schema and easier query
    • normalized-> more complex relationships, complex queries, less redundancy
