Project Nessie is a new open source metastore that builds on table formats such as Apache Iceberg and Delta Lake to deliver multi-table, multi-engine transactions. In addition, Nessie delivers Git-like semantics for data lakes, including commits, tags and branches. By using versioning concepts, users can work in an entirely new way, experimenting or preparing data without impacting the live view of the data, opening a whole world of possibilities for true DataOps on the data lake.

This talk will discuss the benefits of Nessie and Iceberg and how these technologies can work together in modern data platforms.
