Fireside Chat: Journey to Innovation: Unleashing the Power of Open Source Through Open Governance

The Presto Foundation is the organization that oversees the development of the Presto open source project. Hosted at the Linux Foundation, the Presto Foundation operates under a community governance model with representation from all its members. In this fireside chat, we’ll hear more from Girish Baliga, Chair of the Presto Foundation, on what it actually means to be a Presto Foundation member and why this governance model is so important for open source projects. We’ll also talk with Vikram Murali of IBM, the newest member of the Presto Foundation. He’ll share more about IBM’s journey to Presto, how they’re using it in IBM’s new watsonx.data lakehouse, and why the Presto Foundation played an important role in IBM’s decision to choose Presto.

Scaling Cache for Presto Iceberg Connector – Beinan Wang, Alluxio & Chunxu Tang

While using the Presto Iceberg connector, the in-heap cache in Presto is likely overloaded. In this talk, Beinan and Chunxu will share the design, implementation, and optimization of the off-heap cache to address the scalability challenges. You will learn how to cache Iceberg data and metadata for the Presto Iceberg connector, followed by future work on improving table scans using Apache Arrow.

A Tour of Presto Iceberg Connector – Beinan Wang, Alluxio & Chunxu Tang, Twitter

Apache Iceberg is an open table format for huge analytic datasets. The Presto Iceberg connector consolidates the SQL engine and the table format, to empower high-performant data analytics. Here, Beinan and Chunxu would like to discuss and share the architectural design of the Presto Iceberg connector, advanced Iceberg feature support (such as native iceberg connector, row-level deletion, and iceberg v2 support), and the future roadmap.

Presto and Apache Iceberg – Chunxu Tang, Twitter

Apache Iceberg is an open table format for huge analytic datasets. At Twitter, engineers are working on the Presto-Iceberg connector, aiming to bring high-performance data analytics on Iceberg to the Presto ecosystem. Here, Chunxu would like to share what they have learned during the development, hoping to shed light on the future work of interactive queries.
