Cloud Data Warehouses Are on Their Way Out

Summary

The ecosystem for data tools has been going through rapid and constant evolution over the past several years. These technological shifts have brought about corresponding changes in data and platform architectures for managing data and analytical workflows. In this episode Colleen Tartow shares her insights into the motivating factors and benefits of the most prominent patterns that are in the popular narrative; data mesh and the modern data stack. She also discusses her views on the role of the data lakehouse as a building block for these architectures and the ongoing influence that it will have as the technology matures.

• Hello and welcome to the Data Engineering Podcast, the show about modern data management
• When you’re ready to build your next pipeline, or want to test out the projects you hear about on the show, you’ll need somewhere to deploy it, so check out our friends at Linode. With their new managed database service you can launch a production ready MySQL, Postgres, or MongoDB cluster in minutes, with automated backups, 40 Gbps connections from your application hosts, and high throughput SSDs. Go to dataengineeringpodcast.com/linode today and get a $100 credit to launch a database, create a Kubernetes cluster, or take advantage of all of their other services. And don’t forget to thank them for their continued support of this show!
• Atlan is the metadata hub for your data ecosystem. Instead of locking your metadata into a new silo, unleash its transformative potential with Atlan’s active metadata capabilities. Push information about data freshness and quality to your business intelligence, automatically scale up and down your warehouse based on usage patterns, and let the bots answer those questions in Slack so that the humans can focus on delivering real value. Go to dataengineeringpodcast.com/atlan today to learn more about how Atlan’s active metadata platform is helping pioneering data teams like Postman, Plaid, WeWork & Unilever achieve extraordinary things with metadata and escape the chaos.
• Modern data teams are dealing with a lot of complexity in their data pipelines and analytical code. Monitoring data quality, tracing incidents, and testing changes can be daunting and often takes hours to days or even weeks. By the time errors have made their way into production, it’s often too late and damage is done. Datafold built automated regression testing to help data and analytics engineers deal with data quality in their pull requests. Datafold shows how a change in SQL code affects your data, both on a statistical level and down to individual rows and values before it gets merged to production. No more shipping and praying, you can now know exactly what will change in your database! Datafold integrates with all major data warehouses as well as frameworks such as Airflow & dbt and seamlessly plugs into CI workflows. Visit dataengineeringpodcast.com/datafold today to book a demo with Datafold.
• Tired of deploying bad data? Need to automate data pipelines with less red tape? Shipyard is the premier data orchestration platform built to help your data team quickly launch, monitor, and share workflows in a matter of minutes. Build powerful workflows that connect your entire data stack end-to-end with a mix of your code and their open-source, low-code templates. Once launched, Shipyard makes data observability easy with logging, alerting, and retries that will catch errors before your business team does. So whether you’re ingesting data from an API, transforming it with dbt, updating BI tools, or sending data alerts, Shipyard centralizes these operations and handles the heavy lifting so your data team can finally focus on what they’re good at — solving problems with data. Go to dataengineeringpodcast.com/shipyard to get started automating with their free developer plan today!
• Your host is Tobias Macey and today I’m interviewing Colleen Tartow about her views on the forces shaping the current generation of data architectures

Interview

• Introduction
• How did you get involved in the area of data management?
  • In your opinion as an astrophysicist, how well does the metaphor of a starburst map to your current work at the company of the same name?
• Can you describe what you see as the dominant factors that influence a team’s approach to data architecture and design?
• Two of the most repeated (often mis-attributed) terms in the data ecosystem for the past couple of years are the "modern data stack" and the "data mesh". As someone who is working at a company that can be construed to provide solutions for either/both of those patterns, what are your thoughts on their lasting strength and long-term viability?
• What do you see as the strengths of the emerging lakehouse architecture in the context of the "modern data stack"?
  • What are the factors that have prevented it from being a default choice compared to cloud data warehouses? (e.g. BigQuery, Redshift, Snowflake, Firebolt, etc.)
  • What are the recent developments that are contributing to its current growth?
  • What are the weak points/sharp edges that still need to be addressed? (both internal to the platforms and in the external ecosystem/integrations)
• What are some of the implementation challenges that teams often experience when trying to adopt a lakehouse strategy as the core building block of their data systems?
  • What are some of the exercises that they should be performing to help determine their technical and organizational capacity to support that strategy over the long term?
• One of the core requirements for a data mesh implementation is to have a common system that allows for product teams to easily build their solutions on top of. How do lakehouse/data virtualization systems allow for that?
  • What are some of the lessons that need to be shared with engineers to help them make effective use of these technologies when building their own data products?
  • What are some of the supporting services that are helpful in these undertakings?
• What do you see as the forces that will have the most influence on the trajectory of data architectures over the next 2 – 5 years?
• What are the most interesting, innovative, or unexpected ways that you have seen lakehouse architectures used?
• What are the most interesting, unexpected, or challenging lessons that you have learned while working on the Starburst product?
• When is a lakehouse the wrong choice?
• What do you have planned for the future of Starburst’s technology platform?
