HANDS-ON VIRTUAL LAB Query Data in S3 Using Presto Jan 26 2023 1 

WELCOME TO THE AHANA HANDS-ON VIRTUAL LAB Your Lab Guide: Rohan Pednekar 

Over the next 90 minutes you will: ● Explore and understand Presto ● Get a walk-through of creating a new cluster using Ahana ● Query data sitting in S3 using Presto ● Convert data to different Formats Using Presto ● Run federated queries/joins across multiple sources combining data in S3 and RDS/MYSQL Objective for Today 3 

Agenda 1) Understand the Technology (15-20 mins) a) What is Presto? b) What is Ahana Cloud? 2) Getting your hands dirty (60 mins) 3) Summary and Close Out (5 mins) 4 

Understanding The Technology Presto 

What is Presto? • Open source, distributed MPP SQL query engine • Query in Place • Federated Querying • ANSI SQL Compliant • Designed ground up for fast analytic queries against data of any size • Originally developed at Facebook • Proven on petabytes of data • SQL-On-Anything • Federated pluggable architecture to support many connector • Opensource, hosted on github • https://github.com/prestodb 6

Presto – It’s Exploding Presto is De-Facto SQL Engine https://db-engines.com/en/ranking_trend/relational+dbms Spark SQL vs. Presto “As one of our earliest members, Ahana has been strong supporters of the Presto Foundation since its launch in 2019.”

Presto Architecture 

What makes Presto different? Scalable Architecture Pluggable Connectors Performance 12 

Scalable Architecture • Two roles - coordinator and worker • Easy scale up and scale down • Scale up to 1000 workers • Validated at web scale companies New Worker New Worker Worker Worker Worker Coordinator Data Source Presto Cluster 13

Pluggable Presto Connectors 15 

Presto Connector Data Model • Connector: Driver for a data source. • Example: HDFS, AWS S3, Cassandra, MySQL, SQL Server, Kafka • Catalog: Contains schemas from a data source specified by the connector • Schemas: Namespace to organize tables. • Tables: Set of unordered rows organized into columns with types. 16 

Presto Hive Connector – Data File Types • Supported File Types • ORC • Parquet • Avro • RCFile • CSV • No data ingestion/duplication/movement needed • Query data in-place • SequenceFile • JSON • Text 17 

Introducing Ahana Cloud Fully-Managed Presto Service 

Ahana Cloud for Presto Managed Service • Enables data platform engineers in minutes vs. days • Fully integrated & pre-configured • No ETL, in-place analytics 

Ahana Cloud for Presto Ahana Console (Control Plane) CLUSTER ORCHESTRATION CONSOLIDATED LOGGING SECURITY & ACCESS BILLING & SUPPORT In-VPC Presto Clusters (Compute Plane) AD HOC CLUSTER 1 TEST CLUSTER 2 PROD CLUSTER N Glue S3 RDS Elasticsearch Ahana Cloud Account Ahana console oversees and manages every Presto cluster Customer Cloud Account In-VPC orchestration of Presto clusters, where metadata, monitoring, and data sources reside 

Ahana Cloud – Reference Architecture • Distributed SQL engine with proven scalability • Interactive ANSI SQL queries • Query data where it lives with Federated Connectors (no ETL) • High concurrency • Separation of compute and storage • Cost Management Features 21 

Getting Your Hands Dirty 

Wrapping Up Conclusion and Things to Try 

1. Scale Up and Scale Down your cluster 2. Check your cluster’s PrestoDB Console when running SQL 3. Try queries with more/less workers; how does performance change? 4. Try partitioned datasets Things to try later... 24 

Conclusion In this hands-on workshop you have: 1. About Presto and Ahana Cloud 2. How to effortlessly created and managed Presto clusters 3. Run fast SQL federated queries combining datasets from S3 and MySQL 4. Run presto queries via python 5. Create a simple BI dashboard using SuperSet 25
