And then now with AI, the worst part is that it can run properly, but the numbers are wrong." - Lei"If you talk to anybody working in the BI space, like self-service BI, that has been termed for maybe for the past decade. But I have to say that is a false promise." - Lei"We're saying that we really want those data team to be able to, like, say, what type of data is exposed to, like, say, less technical folks." - Lei"In order to build AI native BI, I would say the focus should be how human interact with AI." - Lei"We believe that, essentially, this BI system or, like, AI BI system would be more like a agent, and then it'll actually looking for, like, business opportunities and insight and surface to you." - Lei"The one common theme I have been experiencing is that normally would work with other business stakeholders, could be marketing, could be operations, could be sales." - Lei"We strongly believe that BI should be stored as code." - Lei"Enterprise data tends to be very noisy, very complex." - Lei"The semantics of itself becomes part of the context for the AI engine." - Lei"Most organizations, the data, like the schema, the kind of business, like metrics and logic, has been constantly evolving." - LeiResourcesFabi.ai - AI-native BI platformFirebolt (firebolt.io) - Cloud data warehouse platformTools & Technologies:Firebolt Core - Free self-hosted query engineLooker - BI PlatformTableau - BI PlatformSisense - BI PlatformSnowflake - Data WarehouseBigQuery - Data WarehousePostgreSQL - DatabaseSQL Alchemy - Database toolkitPandas - Data analysis libraryFor Feedback & Discussions on Firebolt Core:Join Firebolt Discord CommunityJoin Firebolt GitHub DiscussionsFirebolt Core Github Repository Benjamin@Firebolt.io Primary Speakers:Lei Tang  Benjamin Wagner The Data Engineering Show is brought to you by firebolt.io and handcrafted by our friends over at: fame.soPrevious guests include: Joseph Machado of Linkedin, Metthew Weingarten of Disney, Joe Reis and Matt Housely, authors of The Fundamentals of Data Engineering, Zach Wilson of Eczachly Inc, Megan Lieu of Deepnote, Erik Heintare of Bolt, Lior Solomon of Vimeo, Krishna Naidu of Canva, Mike Cohen of Substack, Jens Larsson of Ark, Gunnar Tangring of Klarna, Yoav Shmaria of Similarweb and Xiaoxu Gao of Adyen.Check out our three most downloaded episodes:Zach Wilson on What Makes a Great Data EngineerJoe Reis and Matt Housley on The Fundamentals of Data EngineeringBill Inmon, The Godfather of Data Warehousing

Different infra teams have their Slack channels, and because these technologies are widely used, you have to wait a lot." - Paarth"What we realized is for our engineers to really get help, data sources really should be internal only because we customize lot of these open source engines for making it work at Uber scale." - Paarth"Instead of building a mega scale pipeline that just ingest all data sources and then keeps a central data source solution, we instead are giving users the flexibility to ingest what data sources they want." - Paarth"We had to scale our you can say the whole infrared layer to chunk data faster to be able to create embedding set scale." - Paarth"It almost felt like they're doing what EMR was doing. You have your Hadoop and big data technology, and we needed these pipelines to basically process all this data quickly." - Paarth"We've even evolved from just giving you the right documentation to starting to evolve into a situation where we'll also start taking actions on your behalf." - Paarth"That intuition that comes from building this kind of bot, I feel like that intuition came again as we were starting to see this technology come, and we're like, hey, this looks like where you can pretty much fit all these pieces together." - Paarth"What we have seen with several use cases is agentic genie works well when designed well, when you've analyzed the problem of which type of subproblems the bot should resolve per channel, per use case." - Paarth"I think having a problem in mind always helps that way, the energy is little bit focused and directed." - Paarth"Whatever you're building is not enough because the expectation has already gone to the next level, so the pace is too fast right now." - PaarthResourcesCompanies & Platforms:Uber - ML Platform & EngineeringFirebolt - Cloud Data Warehouse (firebolt.io)Tools & Technologies:Michelangelo - Uber's ML Platform Genie - Uber's On-Call Assistant BotCursor - Developer IDEOpenSearch - Vector DatabaseLangGraph - Agent FrameworkNotable Projects Mentioned:MetaMate (Meta)Query Copilot (Uber)Scale at AI (Meta Meetup)Company Blogs:Uber Engineering Blog - Genie and Query Optimization articles Primary Speakers:Paarth Chotani - Staff Engineer, UberBenjamin - FireboltEldad - FireboltFor Feedback & Discussions on Firebolt Core:Join Firebolt Discord CommunityJoin Firebolt GitHub DiscussionsFirebolt Core Github Repository Benjamin@Firebolt.ioThe Data Engineering Show is brought to you by firebolt.io and handcrafted by our friends over at: fame.soPrevious guests include: Joseph Machado of Linkedin, Metthew Weingarten of Disney, Joe Reis and Matt Housely, authors of The Fundamentals of Data Engineering, Zach Wilson of Eczachly Inc, Megan Lieu of Deepnote, Erik Heintare of Bolt, Lior Solomon of Vimeo, Krishna Naidu of Canva, Mike Cohen of Substack, Jens Larsson of Ark, Gunnar Tangring of Klarna, Yoav Shmaria of Similarweb and Xiaoxu Gao of Adyen.Check out our three most downloaded episodes:Zach Wilson on What Makes a Great Data EngineerJoe Reis and Matt Housley on The Fundamentals of Data EngineeringBill Inmon, The Godfather of Data Warehousing
