Ahana Sessions at PrestoCon

December 8 at 1:00 pm PT – “Building Large Scale Query Operators and Window Functions for Prestissimo Using Velox” by Aditi Pandit, Presto/Velox Contributor and Principal Software Engineer, Ahana.

In this talk, Aditi will throw the covers back on some of the most interesting portions of working on Prestissimo and Velox. The talk will be based on the experience of implementing window functions in Velox. It will cover the nitty gritty on the vectorized operator, memory management and spilling. This talk is perfect for anyone who is using Presto in production and wants to understand more about the internals, or someone who is new to Presto and is looking for a deep technical understanding of the architecture.

December 8 at 2:30 pm PT – “The Future of Presto’s Query Optimizer” by Bill McKenna, Query Optimizer Pioneer and Author and Principal Software Engineer, Ahana.

In this talk, you will hear Bill, the architect for the query optimizer that became the code base of the Amazon Redshift query optimizer, and co-author of The Volcano Optimizer Generator: Extensibility and Efficient Search go into detail about the state of modern query optimizers, and how Presto stacks up against them and where it will go in the near future. This is a must-attend session for attendees interested in database theory.

Presto continues to be recognized as an industry-leading fast and reliable SQL engine for data analytics and the open data lakehouse.
