The Berkeley DB Data Store product is an embeddable, high-performance data store. This product - supports multiple concurrent threads of control, including multiple - processes and multiple threads of control within a process. - However, Berkeley DB Data Store does not support locking, - and hence does not guarantee correct behavior if more than one - thread of control is updating the database at a time. The Berkeley DB Data Store is - intended for use in read-only applications or applications which can - guarantee no more than one thread of control updates the - database at a time.

Berkeley DB High Availability

Berkeley DB High Availability

-

The Berkeley DB High Availability product adds support for data replication. A single master system - handles all updates, and distributes these updates to multiple replicas. The number of replicas depends on the application requirements. All replicas can handle read requests during - normal processing. If the master system fails for any reason, one of - the replicas takes over as the new master system, and distributes - updates to the remaining replicas.
