network partition

A network partition, usually inadvertently, separates a network

into disconnected parts. For example, due to link failures,

a 20-node network could become two unconnected 10-node

networks. This would constitute a network partition.

node

nontransactional message

A message containing data that does not contain any part of

a transaction such as a broadcast or diagnostic message. See

transactional message.

partition

RTR transactions can be sent to a specified key range of a

database or a partition. This is data-content routing and is

handled by RTR when so programmed in the application and

specified by the system administrator. For example, a database

with keys from A to Z can be partitioned into key ranges from A

to I, J to R, and S to Z. A partition can be in one of three states:

primary, standby, and shadow. See also network partition.

partition properties

Information about the attributes of a partition.

polling

A processing method where the application polls for incoming

messages.
