Session: Apache XTable, cross table interoperability with Delta, Iceberg, and Hudi

Ashvin Agrawal, Research Software Engineer @ Microsoft

Dipankar Mazumdar, Staff Data Engineer Advocate @ Onehouse

Apache XTable is a new open source project incubating in the Apache Software Foundation that unlocks omni-directional interoperability between the popular lakehouse projects Delta Lake, Apache Iceberg, and Apache Hudi. With a budding community over the past year, XTable has proven to be a bridge of unification for the data lakehouse industry.

In this session, we will highlight what is new in the project and the community. We will review the technical details of how the metadata translation works and showcase real-world examples of how users have adopted the project. Watch this session to see a live demo of how to use XTable with a variety of open source query engines including Spark, Presto, Trino, Flink, and more.
