Ahana and Ahana customer sessions at PrestoCon
July 21 at 9:35 a.m. PT — “Free-Forever Managed Service for Presto for your Cloud-Native Open SQL Lakehouseby Wen Phan, Director of Product Management, Ahana
Getting started with a DIY approach to setting up an open SQL Lakehouse can be difficult and time-consuming. Ahana Cloud Community Edition greatly simplifies it and gives users the ability to learn and validate Presto for their open SQL Lakehouse, for free. In this session, Wen will demonstrate how easy it is to sign up, get up, and use the Ahana Cloud Community Edition to query over a lake.
July 21 at 10:30 a.m. PT — “How Blinkit Builds an Open Data Lakehouse with Presto on AWSby Akshay Agarwal, Software Engineer, Blinkit; and Satyam Krishna, Director of Engineering, Blinkit
Blinkit, India’s leading instant delivery service, uses Presto on AWS to help them deliver on their “everything is delivered in 10 minutes” promise. In this session, Satyam and Akshay will explain why they switched to Presto on S3 from their cloud data warehouse for more flexibility and better pricing performance. They will also share more about their open data lakehouse architecture which includes Presto as SQL engine for ad-hoc reporting, Ahana as SaaS for Presto, Apache Hudi and Iceberg to help manage transactions, and AWS S3 as data lake.
July 21 at 11:00 a.m. PT — “Optimizing Query Execution for Broadcast Join Using Replicated Reads Strategy“, by George Wang, Senior Software Engineer, Ahana
Today, Presto supports broadcast join by having a worker extract data from a small data source to create a hash table, then send the entire data over the network to all other workers for a hash search probed by a large data source. This can be optimized by a new query execution strategy, as source data from small tables is fetched directly by all workers, which is known as replicated reads from dimension tables. This feature comes with a nice caching property as all N worker nodes now participate in parsing data from remote sources. The table scan operation for dimension tables can be cached for all worker nodes. Also, there will be better resource utilization as presto scheduler can now reduce number of dial plan fragment to execute as same workers execute tasks in parallel in single step to reduce data mixing.
July 21 at 2:25 p.m. PT – “Ready for the Open Data Lakehouse», panel discussion moderated by Eric Kavanagh, CEO, Bloor Group with Dave Simmen, CTO and co-founder, Ahana; Girish Baliga, President of the Presto Foundation and Senior Director of Engineering, Uber; Biswapesh Chattopadhyay, Technical Lead, DI Compute, Meta; and Ali LeClerc, Presto Outreach Committee Chair and Community Leader, Ahana
Today’s digital-native businesses need a modern data infrastructure that can handle data management and data-driven analytics for the ever-increasing amount of data needed to conduct business. Specifically, they face challenges such as complexity, cost, and lock-in. An Open SQL Data Lakehouse approach enables flexibility and better cost performance by leveraging open technologies and formats. Join us for this panel where the main technologists of the Presto open source project will share their vision of SQL Data Lakehouse and why Presto is an essential component.
