+<h2 id="trino">Trino</h2>
+
+<p><a href="https://trino.io/">Trino</a> (formerly PrestoSQL) was forked off
PrestoDB few years ago. Hudi supports snapshot queries on Copy-On-Write tables
& Read Optimized queries
+on Merge-On-Read tables at the moment, through the initial input format based
integration in PrestoDB (pre forking). This approach has
+known performance limitations with very large tables, which has been since
fixed on PrestoDB. We are working on replicating the same fixes on Trino as
well.</p>
+
+<p>To query Hudi tables on Trino, please place the <code
class="highlighter-rouge">hudi-presto-bundle</code> jar into the Hive connector
installation <code
class="highlighter-rouge"><trino_install>/plugin/hive-hadoop2</code>.</p>
