<p>A function that divides input messages into multiple sequences of messages or concatenates multiple sequences of messages into a single messages sequence.</p>
<h3>Details</h3>
<h4>group by number of messages</h4>
<p>groups incoming messages into sequences of messages with specified counts. The output message group can be overwrapped.</p>
<h4>group by interval in seconds</h4>
<p>groups incoming messages received withn specified interval into sequences of messages. </p>
<h4>concatenate message groups</h4>
<p>creates a message sequence based on <code>topic</code> value of incoming message sequences.</p>
<p>Target and order of concatenated sequences are specified by <code>Topics</code> value. Selection of concatenated message groups is based on arrival of first message of the group.</p>
<p><b>Note:</b> This node internally keeps messages for its operation. In order to prevent unexpected memory usage, maximum number of messages kept can be specified. Default is no limit on number of messages.
<ul>
<li><code>batchMaxKeptMsgsCount</code> property set in <b>settings.js</b>.</li>
</ul>
