  • Enum Constant Details

    • SYNC

      public static final TouchMode SYNC
      Delay read operations until the other owners confirm updating the timestamp of the entry
    • ASYNC

      public static final TouchMode ASYNC
      Send touch commands to other owners, but do not wait for their confirmation. This allows read operations to return the value of a key even if another node has started expiring it. When that happens, the read won't extend the lifespan of the key.
