      Extract from the source code related to 'derby.storage.rowLocking' derby engine property definition:

      /**

      • In cloudscape products which support Row Level Locking (rll), use this
      • property to disable rll. Application's which use rll will use more
      • system resources, so if an application knows that it does not need rll
      • then it can use this system property to force all locking in the system
      • to lock at the table level.
        *
      • This property can be set to the boolean values "true" or "false". * Setting the property to true is the same as not setting the property at
      • all, and will result in rll being enabled. Setting the property to
      • false disables rll.
        *
        **
