• Hello and welcome to the Data Engineering Podcast, the show about modern data management
• If you lead a data team, you know this pain: Every department needs dashboards, reports, custom views, and they all come to you. So you're either the bottleneck slowing everyone down, or you're spending all your time building one-off tools instead of doing actual data work. Retool gives you a way to break that cycle. Their platform lets people build custom apps on your company data—while keeping it all secure. Type a prompt like 'Build me a self-service reporting tool that lets teams query customer metrics from Databricks—and they get a production-ready app with the permissions and governance built in. They can self-serve, and you get your time back. It's data democratization without the chaos. Check out Retool at dataengineeringpodcast.com/retool today and see how other data teams are scaling self-service. Because let's be honest—we all need to Retool how we handle data requests.
• Your host is Tobias Macey and today I'm interviewing Tim Sehn about Dolt, a version controlled database engine and its applications for agentic workflows

Interview

• Introduction
• How did you get involved in the area of data management?
• Can you describe what Dolt is and the story behind it?
• What are the key use cases that you are focused on solving by adding version control to the database layer?
• There are numerous projects related to different aspects of versioning in different data contexts (e.g. LakeFS, Datomic, etc.). What are the versioning semantics that you are focused on?
• You position Dolt as "the database for AI". How does data versioning relate to AI use cases?
• What types of AI systems are able to make best use of Dolt's versioning capabilities?
• Can you describe how Dolt and Doltgres are implemented?
• How have the design and scope of the project changed since you first started working on it?
• What are some of the architecture and integration patterns around relational databases that change when you introduce version control semantics as a core primitive?
• What are some anti-patterns that you have seen teams develop around Dolt's versioning functionality?
• What are the most interesting, innovative, or unexpected ways that you have seen Dolt used?
• What are the most interesting, unexpected, or challenging lessons that you have learned while working on Dolt?
• When is Dolt the wrong choice?
• What do you have planned for the future of Dolt?
