+## Trino
+
+[Trino](https://trino.io/) (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.
+
+To query Hudi tables on Trino, please place the `hudi-presto-bundle` jar into
the Hive connector installation `<trino_install>/plugin/hive-hadoop2`.
