ThrottleDMLPerformance

Use this component to control the speed the pipeline processes direct mail messages. This controls the load on the Simple Mail Transfer Protocol (SMTP) server.

Intended use: Direct Mailer pipeline, Throttle stage.

Configuration Values

None.

Values Read

The ThrottleDMLPerformance component reads the following values from the indicated dictionaries.

Key Dictionary Description
delay_msec Context The delay between messages in milliseconds.

Values Written

None.

Remarks

An SMTP server can be overwhelmed by receiving too many messages at a time. For this reason, a direct mail pipeline may need to slow down delivery of messages to the server.

The ThrottleDMLPerformance component simply waits the number of milliseconds specified by the delay_msec key. The Direct Mailer service calculates the delay needed to maintain an appropriate delivery rate. It then sets the delay_msec value in the Context dictionary, which is read by the ThrottleDMLPerformance component.
