How to build an Open Data Lakehouse Analytics Stack Shawn Gordon Sr. Developer Advocate

2 Why Open Data Lake Analytics? Enterprise Data Beyond Enterprise Data IoT, Third-party, Telemetry, Event 1000X More Data Terabytes to Petabytes Open & Flexible Open Source, Open Formats Reporting & Dashboarding Data Science In-data lake transformation Reporting & Dashboarding Data Warehouse Open Data Lakes

3 What is Open Data Lake Analytics

4 The Traditional Data Warehouse • Relational Database • Columnar Structure • In-Database Analytics • Structured Data • Modeled Data • Extract, Transform, Load • SQL Access Challenges • Expensive • Difficult to Manage • Costly to Maintain • Limited Data • Limited Access 4

5 The Drivers Behind Modernization Digital Transformation Real Time Events Modern Processing Techniques More Data Fast Data Smart Data The Deconstructed Database

6 The Traditional Data Lake • File System Data Store / Object Store • Structured / Semi-Structured Data • Ingestion • Discovery • Data Science • Notebook and Python Access • Less expensive, but… • Good enough performance • Supports ~70% of DW workloads • Different approach to governance 6

Merging the Data Warehouse and the Data Lake with a Distributed Query Engine 11 1. SQL Access 2. Data Lake and Data Warehouse Access 3. Unified Analytics 4. Distributed Queries 5. Limitless Scale 6. Complex Data Types • Leverage Resources • Better Insight • More Use Cases • Leverage Platforms • Remove Limits • Amplified Insight

25 Challenges with SQL on Open Data Lakes Cloud DW / AWS Serverless options get very expensive for growing data volumes ▪ Cloud data warehouse costs grow much faster than compute engine costs ▪ Serverless options like AWS Athena charge /query and get expensive “Do it yourself” approach is complicated ▪ Big data skills in platform teams are limited ▪ Presto is complicated and operationally very time consuming Presto on AWS like AWS Athena has limited capabilities and doesn’t scale ▪ Limited concurrency of 20 per account ▪ No visibility into cluster logs, query logs, no flexibility / control on scale
