Let Your Analysts Build A Data Lakehouse With Cuelake

Summary

Data lakes have been gaining popularity alongside an increase in their sophistication and usability. Despite improvements in performance and data architecture they still require significant knowledge and experience to deploy and manage. In this episode Vikrant Dubey discusses his work on the Cuelake project which allows data analysts to build a lakehouse with SQL queries. By building on top of Zeppelin, Spark, and Iceberg he and his team at Cuebook have built an autoscaled cloud native system that abstracts the underlying complexity.

• Are you bored with writing scripts to move data into SaaS tools like Salesforce, Marketo, or Facebook Ads? Hightouch is the easiest way to sync data into the platforms that your business teams rely on. The data you’re looking for is already in your data warehouse and BI tools. Connect your warehouse to Hightouch, paste a SQL query, and use their visual mapper to specify how data should appear in your SaaS systems. No more scripts, just SQL. Supercharge your business teams with customer data using Hightouch for Reverse ETL today. Get started for free at dataengineeringpodcast.com/hightouch.
• Have you ever had to develop ad-hoc solutions for security, privacy, and compliance requirements? Are you spending too much of your engineering resources on creating database views, configuring database permissions, and manually granting and revoking access to sensitive data? Satori has built the first DataSecOps Platform that streamlines data access and security. Satori’s DataSecOps automates data access controls, permissions, and masking for all major data platforms such as Snowflake, Redshift and SQL Server and even delegates data access management to business users, helping you move your organization from default data access to need-to-know access. Go to dataengineeringpodcast.com/satori today and get a $5K credit for your next Satori subscription.
• Your host is Tobias Macey and today I’m interviewing Vikrant Dubey about Cuebook and their Cuelake project for building ELT pipelines for your data lakehouse entirely in SQL

Interview

• Introduction
• How did you get involved in the area of data management?
• Can you describe what Cuelake is and the story behind it?
• There are a number of platforms and projects for running SQL workloads and transformations on a data lake. What was lacking in those systems that you are addressing with Cuelake?
• Who are the target users of Cuelake and how has that influenced the features and design of the system?
• Can you describe how Cuelake is implemented?
  • What was your selection process for the various components?
• What are some of the sharp edges that you have had to work around when integrating these components?
• What involved in getting Cuelake deployed?
• How are you using Cuelake in your work at Cuebook?
• Given your focus on machine learning for anomaly detection of business metrics, what are the challenges that you faced in using a data warehouse for those workloads?
  • What are the advantages that a data lake/lakehouse architecture maintains over a warehouse?
  • What are the shortcomings of the lake/lakehouse approach that are solved by using a warehouse?
• What are the most interesting, innovative, or unexpected ways that you have seen Cuelake used?
• What are the most interesting, unexpected, or challenging lessons that you have learned while working on Cuelake?
• When is Cuelake the wrong choice?
• What do you have planned for the future of Cuelake?
