Today, data lakes are widely used and have become extremely affordable as data volumes have grown. However, they are only meant for storage and by themselves provide no direct value. With up to 80% of data stored in the data lake today, how do you unlock the value of the data lake? The value lies in the compute engine that runs on top of a data lake. Join us for this webinar where Ahana co-founder and Chief Product Officer Dipti Borkar will discuss how to unlock the value of your data lake with the emerging Open Data Lake analytics architecture. Dipti will cover: -Open Data Lake analytics - what it is and what use cases it supports -Why companies are moving to an open data lake analytics approach -Why the open source data lake query engine Presto is critical to this approach

• 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

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
