Select Star - The Data Discovery Platform

Summary

Industrial applications are one of the primary adopters of Internet of Things (IoT) technologies, with business critical operations being informed by data collected across a fleet of sensors. Vopak is a business that manages storage and distribution of a variety of liquids that are critical to the modern world, and they have recently launched a new platform to gain more utility from their industrial sensors. In this episode Mário Pereira shares the system design that he and his team have developed for collecting and managing the collection and analysis of sensor data, and how they have split the data processing and business logic responsibilities between physical terminals and edge locations, and centralized storage and compute.

• 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. 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 subscription
• So now your modern data stack is set up. How is everyone going to find the data they need, and understand it? Select Star is a data discovery platform that automatically analyzes & documents your data. For every table in Select Star, you can find out where the data originated, which dashboards are built on top of it, who’s using it in the company, and how they’re using it, all the way down to the SQL queries. Best of all, it’s simple to set up, and easy for both engineering and operations teams to use. With Select Star’s data catalog, a single source of truth for your data is built in minutes, even across thousands of datasets. Try it out for free and double the length of your free trial today at dataengineeringpodcast.com/selectstar. You’ll also get a swag package when you continue on a paid plan.
• Your host is Tobias Macey and today I’m interviewing Mário Pereira about building a data management system for globally distributed IoT sensors at Vopak

Interview

• Introduction
• How did you get involved in the area of data management?
• Can you describe what Vopak is and what kinds of information you rely on to power the business?
• What kinds of sensors and edge devices are you using?
  • What kinds of consistency or variance do you have between sensors across your locations?
• How much computing power and storage space do you place at the edge?
  • What level of pre-processing/filtering is being done at the edge and how do you decide what information needs to be centralized?
  • What are some examples of decision-making that happens at the edge?
• Can you describe the platform architecture that you have built for collecting and processing sensor data?
  • What was your process for selecting and evaluating the various components?
• How much tolerance do you have for missed messages/dropped data?
• How long are your data retention periods and what are the factors that influence that policy?
• What are some statistics related to the volume, variety, and velocity of your data?
  • What are the end-to-end latency requirements for different segments of your data?
• What kinds of analysis are you performing on the collected data?
• What are some of the potential ramifications of failures in your system? (e.g. spills, explosions, spoilage, contamination, revenue loss, etc.)
• What are some of the scaling issues that you have experienced as you brought your system online?
• How have you been managing the decision making prior to implementing these technology solutions?
• What are the new capabilities and business processes that are enabled by this new platform?
• What are the most interesting, innovative, or unexpected ways that you have seen your data capabilities applied?
• What are the most interesting, unexpected, or challenging lessons that you have learned while working on building an IoT collection and aggregation platform at global scale?
• What do you have planned for the future of your IoT system?
