** An "RBU update" transaction is subject to the following limitations:

** guarantee that a single update process will run for long enough to apply 
** the entire update, for example because the update is being applied on a 
** mobile device that is frequently rebooted. Even after the writer process 
** has committed one or more sub-transactions, other database clients continue
** to read from the original database snapshot. In other words, partially 
** applied transactions are not visible to other clients. 
**
** "RBU" stands for "Resumable Bulk Update". As in a large database update
** transmitted via a wireless network to a mobile device. A transaction
** applied using this extension is hence refered to as an "RBU update".
