Message Delivery Modes
PERSISTENT
|
The message is persisted on disk by the server. This mode
ensures delivery of messages to a destination.
|
NON-PERSISTENT
|
Omits the overhead of persisting the message on disk. If
Authorization is disabled on the server, the server doesn't
send a confirmation to the message producer. Regardless of
Authorization is enabled or disabled, we can use the
npsend_check_mode parameter in tibemsd.conf file to specify
the condition under which the server is to send the
confirmation of NON-PERSISTENT messages to the producer.
|
RELIABLE_DELIVERY
|
Omits the overhead of persisting the message on disk. The
server doesn't send a confirmation to the message producer
to improve the performance regardless of the authorozation
setting.
