CDS data is maintained in a loosely consistent manner. This means that when the writeable copy of a replicated name is updated, the read-only copies may not be updated for some period of time, and applications reading from those nonsynchronized copies can receive stale data. This is in contrast to distributed databases, which use multiphase commit protocols that prevent readers from accessing potentially stale or inconsistent data while the writes are being propagated to all copies of the data. It is possible to specifically request data from the master copy, which is guaranteed to be up-to-date, but replication advantages are then lost. This should only be done when it is important to obtain current data.
