<p>Event listeners are plugins that allow streaming of query events, such as query
started or query finished, to an external system.</p>
<p>Using an event listener you can process and store the query events in a separate
system for long periods of time. Some of these external systems can be queried
with Trino for further analysis or reporting.</p>
<p>The following event listeners are available:</p>
<div class="toctree-wrapper compound">
<ul>
<li class="toctree-l1"><a class="reference internal" href="admin/event-listeners-http.html">HTTP event listener</a></li>
<li class="toctree-l1"><a class="reference internal" href="admin/event-listeners-kafka.html">Kafka event listener</a></li>

<li class="toctree-l1"><a class="reference internal" href="admin/event-listeners-openlineage.html">OpenLineage event listener</a></li>
</ul>

<p>Unrelated to event listeners, the coordinator stores information about recent
queries in memory for usage by the <a class="reference internal" href="admin/web-interface.html"><span class="doc std std-doc">Web UI</span></a> - see also
<code class="docutils literal notranslate"><span class="pre">query.max-history</span></code> and <code class="docutils literal notranslate"><span class="pre">query.min-expire-age</span></code> in
