|
|
<p>Introduces a delay into a flow or rate limits messages.</p>
|
|
<p>Default delay is 5 seconds and rate limit of 1 msg/second, but both can be configured.</p>
|
|
<p>If you select a rate limit you may optionally discard any intermediate messages that arrive.</p>
|
|
<p>The "topic based fair queue" adds messages to a release queue tagged by their <b>msg.topic</b> property.
|
|
At each "tick", derived from the rate, the next "topic" is released.
|
|
Any messages arriving on the same topic before release replace those in that position in the queue.
|
|
So each "topic" gets a turn - but the most recent value is always the one sent.</p>
