Summary
One of the perennial challenges of data analytics is having a consistent set of definitions, along with a flexible and performant API endpoint for querying them. In this episode Artom Keydunov and Pavel Tiunov share their work on Cube.js and the various ways that it is being used in the open source community.

Hello and welcome to the Data Engineering Podcast, the show about modern data managementWhen 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. With simple pricing, fast networking, object storage, and worldwide data centers, you’ve got everything you need to run a bulletproof data platform. Go to dataengineeringpodcast.com/linode today and get a $100 credit to try out a Kubernetes cluster of your own. And don’t forget to thank them for their continued support of this show!Atlan is a collaborative workspace for data-driven teams, like Github for engineering or Figma for design teams. By acting as a virtual hub for data assets ranging from tables and dashboards to SQL snippets & code, Atlan enables teams to create a single source of truth for all their data assets, and collaborate across the modern data stack through deep integrations with tools like Snowflake, Slack, Looker and more. Go to dataengineeringpodcast.com/atlan today and sign up for a free trial. If you’re a data engineering podcast listener, you get credits worth $3000 on an annual subscriptionModern 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. Datafold helps Data teams gain visibility and confidence in the quality of their analytical data through data profiling, column-level lineage and intelligent anomaly detection. Datafold also helps automate regression testing of ETL code with its Data Diff feature that instantly shows how a change in ETL or BI code affects the produced data, both on a statistical level and down to individual rows and values. Datafold integrates with all major data warehouses as well as frameworks such as Airflow & dbt and seamlessly plugs into CI workflows. Go to dataengineeringpodcast.com/datafold today to start a 30-day trial of Datafold.Your host is Tobias Macey and today I’m interviewing Artyom Keydunov and Pavel Tiunov about Cube.js a framework for building analytics APIs to power your applications and BI dashboardsInterview
IntroductionHow did you get involved in the area of data management?Can you describe what Cube is and the story behind it?What are the main use cases and platform architectures that you are focused on?Who are the target personas that will be using and managing Cube.js?The name comes from the concept of an OLAP cube. Can you discuss the applications of OLAP cubes and their role in the current state of the data ecosystem?How does the idea of an OLAP cube compare to the recent focus on a dedicated metrics layer?What are the pieces of a data platform that might be replaced by Cube.js?Can you describe the design and architecture of the Cube platform?How has the focus and target use case for the Cube platform evolved since you first started working on it?One of the perpetually hard problems in computer science is cache management. How have you approached that challenge in the pre-aggregation layer of the Cube framework?What is your overarching design philosophy for the API of the Cube system?Can you talk through the workflow of someone building a cube and querying it from a downstream system?What do the iteration cycles look like as you go from initial proof of concept to a more sophisticated usage of Cube.js?What are some of the data modeling steps that are needed in the source systems?The perennial problem of embedding SQL into another host language or DSL is how to deal with validation and developer tooling. What are the utilities that you and the community have built to reduce friction while writing the definitions of a cube?What are the methods available for maintaining visibility across all of the cubes defined within and across installations of Cube.js?What are the opportunities for composing multiple cubes together to form a higher level aggregation?What are the most interesting, innovative, or unexpected ways that you have seen Cube.js used?What are the most interesting, unexpected, or challenging lessons that you have learned while working on Cube?When is Cube the wrong choice?What do you have planned for the future of Cube?Contact Info
