<p>Creates sequences of messages based on various rules.</p>
|
|
<h3>Details</h3>
|
|
<p>There are three modes for creating message sequences:</p>
|
|
<dl>
|
|
<dt>Number of messages</dt>
|
|
<dd>groups messages into sequences of a given length. The <b>overlap</b>
|
|
option specifies how many messages at the end of one sequence should be
|
|
repeated at the start of the next sequence.</dd>
|
|
|
|
<dt>Time interval</dt>
|
|
<dd>groups messages that arrive within the specified interval. If no messages
|
|
arrive within the interval, the node can optionally send on an empty message.</dd>
|
|
|
|
<dt>Concatenate Sequences</dt>
|
|
<dd>creates a message sequence by concatenating incoming sequences. Each message
|
|
must have a <code>msg.topic</code> property and a <code>msg.parts</code> property
|
|
identifying its sequence. The node is configured with a list of <code>topic</code>
|
|
values to identify the order sequences are concatenated.
|
|
</dd>
|
|
</dl>
|
|
<h4>Storing messages</h4>
|
|
<p>This node will buffer messages internally in order to work across sequences. The
|
|
runtime setting <code>nodeMessageBufferMaxLength</code> can be used to limit how many messages nodes
|
|
will buffer.</p>
