• Strong Consistency as of December 2020:
• After a:
  • Successful write of a new object (new PUT)
  • or an overwrite or delete of an existing object (overwrite PUT or DELETE)
• any:
  • subsequent read request immediately receives the latest version of the object (read after write consistency)
  • subsequent request immediately reflects changes (list consistency)
• Available at no additional costs, without any performance impact
