NON_PERSISTENT

Sending a NON_PERSISTENT message omits the overhead of persisting the message on disk to improve performance.

If authorization is disabled on the server, the server does not send a confirmation to the message producer.

If authorization is enabled on the server, the default condition is for the producer to wait for the server to reply with a confirmation in the same manner as when using PERSISTENT mode.

Regardless of whether authorization is enabled or disabled, you can use the npsend_check_mode parameter in the tibemsd.conf file to specify the conditions under which the server is to send confirmation of NON_PERSISTENT messages to the producer. See the description for npsend_check_mode for details.
