Cloud Native Data Orchestration For Machine Learning And Data Engineering With Flyte - Episode 291


Machine learning has become a meaningful target for data applications, bringing with it an increase in the complexity of orchestrating the entire data flow. Flyte is a project that was started at Lyft to address their internal needs for machine learning and integrated closely with Kubernetes as the execution manager. In this episode Ketan Umare and Haytham Abuelfutuh share the story of the Flyte project and how their work at Union is focused on supporting and scaling the code and community that has made Flyte successful.

RudderStack Logo

RudderStack provides all your customer data pipelines in one platform. You can collect, transform, and route data across your entire stack with its event streaming, ETL, and reverse ETL pipelines.

RudderStack’s warehouse-first approach means it does not store sensitive information, and it allows you to leverage your existing data warehouse/data lake infrastructure to build a single source of truth for every team.

RudderStack also supports real-time use cases. You can Implement RudderStack SDKs once, then automatically send events to your warehouse and 150+ business tools, and you’ll never have to worry about API changes again.

Kyligence Logo

Kyligence was founded in 2016 by the original creators of Apache Kylin™,  the leading open source OLAP for Big Data. Kyligence offers an Intelligent OLAP Platform to simplify multidimensional analytics for cloud data lake. Its AI-augmented engine detects patterns from most frequently asked business queries, builds governed data marts automatically and brings metrics accountability on the data lake to optimize data pipeline and avoid excessive number of tables. It provides a unified SQL interface between the cloud object store, cubes, indexes and underlying data sources with a cost-based smart query router for business intelligence, ad-hoc analytics and data services at PB-scale.

Kyligence is trusted by global leaders in financial services, manufacturing and retail industries including UBS, China Construction Bank, China Merchants Bank, Pingan Bank, MetLife, Costa and Appzen. With technology partnership with Microsoft, Amazon, Tableau and Huawei, Kyligence is on a mission to simplify and govern data lakes to be productive for critical business analytics and data services.

Kyligence is dual headquartered in San Jose, CA, United States and Shanghai, China, and is backed by leading investors including Redpoint Ventures, Cisco, Broadband Capital, Shunwei Capital, Eight Roads Ventures, Coatue Management, SPDB International, CICC, Gopher Assets, Guofang Capital, ASG, Jumbo Sheen Fund, and Puxin Capital.

Your data platform needs to be scalable, fault tolerant, and performant, which means that you need the same from your cloud provider. Linode has been powering production systems for over 17 years, and now they’ve launched a fully managed Kubernetes platform. With the combined power of the Kubernetes engine for flexible and scalable deployments, and features like dedicated CPU instances, GPU instances, and object storage you’ve got everything you need to build a bulletproof data pipeline. If you go to today you’ll even get a $100 credit to use on building your own cluster, or object storage, or reliable backups, or… And while you’re there don’t forget to thank them for being a long-time supporter of the Data Engineering Podcast!


  • 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 managed Kubernetes platform it’s now even easier to deploy and scale your workflows, or try out the latest Helm charts from tools like Pulsar and Pachyderm.

  • Data lake architectures provide the best combination of massive scalability and cost reduction, but they aren’t always the most performant option. That’s why Kyligence has built on top of the leading open source OLAP engine for data lakes, Apache Kylin. With their AI augmented engine they detect patterns from your critical queries, automatically build data marts with optimized table structures, and provide a unified SQL interface across your lake, cubes, and indexes. Their cost-based query router will give you interactive speeds across petabyte scale data sets for BI dashboards and ad-hoc data exploration. Stop struggling to speed up your data lake.

  • Your host is Tobias Macey and today I’m interviewing Ketan Umare and Haytham Abuelfutuh about Flyte, the open source and kubernetes-native orchestration engine for your data systems


  • Introduction
  • How did you get involved in the area of data management?
  • Can you describe what Flyte is and the story behind it?
  • What was missing in the ecosystem of available tools that made it necessary/worthwhile to create Flyte?
  • Workflow orchestrators have been around for several years and have gone through a number of generational shifts. How would you characterize Flyte’s position in the ecosystem?
