Summary Data governance is a complex endeavor, but scaling it to meet the needs of a complex or globally distributed organization requires a well considered and coherent strategy. In this episode Tim Ward describes an architecture that he has used successfully with multiple organizations to scale compliance. By treating it as a graph problem, where each hub in the network has localized control with inheritance of higher level controls it reduces overhead and provides greater flexibility. Tim provides useful examples for understanding how to adopt this approach in your own organization, including some technology recommendations for making it maintainable and scalable. If you are struggling to scale data quality controls and governance requirements then this interview will provide some useful ideas to incorporate into your roadmap.

If data is copied between hubs, how are record updates accounted for to ensure that they are replicated to the hubs that hold a copy of that entity? How are access controls and data masking managed to ensure that various compliance regimes are honored? In addition to compliance issues, another challenge of distributed data repositories is the

Summary Building applications on top of unbounded event streams is a complex endeavor, requiring careful integration of multiple disparate systems that were engineered in isolation. The ksqlDB project was created to address this state of affairs by building a unified layer on top of the Kafka ecosystem for stream processing. Developers can work with the SQL constructs that they are familiar with while automatically getting the durability and reliability that Kafka offers. In this episode Michael Drogalis, product manager for ksqlDB at Confluent, explains how the system is implemented, how you can use it for building your own stream processing applications, and how it fits into the lifecycle of your data infrastructure. If you have been struggling with building services on low level streaming interfaces then give this episode a listen and try it out for yourself.

Explore powerful SAS analytics and the Internet of Things! The world that we live in is more connected than ever before. The Internet of Things (IoT) consists of mechanical and electronic devices connected to one another and to software through the internet. Businesses can use the IoT to quickly make intelligent decisions based on massive amounts of data gathered in real time from these connected devices. IoT increases productivity, lowers operating costs, and provides insights into how businesses can serve existing markets and expand into new ones. Intelligence at the Edge: Using SAS with the Internet of Things is for anyone who wants to learn more about the rapidly changing field of IoT. Current practitioners explain how to apply SAS software and analytics to derive business value from the Internet of Things. The cornerstone of this endeavor is SAS Event Stream Processing, which enables you to process and analyze continuously flowing events in real time. With step-by-step guidance and real-world scenarios, you will learn how to apply analytics to streaming data. Each chapter explores a different aspect of IoT, including the analytics life cycle, monitoring, deployment, geofencing, machine learning, artificial intelligence, condition-based maintenance, computer vision, and edge devices.

Summary Misaligned priorities across business units can lead to tensions that drive members of the organization to build data and analytics projects without the guidance or support of engineering or IT staff. The availability of cloud platforms and managed services makes this a viable option, but can lead to downstream challenges. In this episode Sean Knapp and Charlie Crocker share their experiences of working in and with companies that have dealt with shadow IT projects and the importance of enabling and empowering the use and exploration of data and analytics. If you have ever been frustrated by seemingly draconian policies or struggled to align everyone on your supported platform, then this episode will help you gain some perspective and set you on a path to productive collaboration.

Summary Every business collects data in some fashion, but sometimes the true value of the collected information only comes when it is combined with other data sources. Data trusts are a legal framework for allowing businesses to collaboratively pool their data. This allows the members of the trust to increase the value of their individual repositories and gain new insights which would otherwise require substantial effort in duplicating the data owned by their peers. In this episode Tom Plagge and Greg Mundy explain how the BrightHive platform serves to establish and maintain data trusts, the technical and organizational challenges they face, and the outcomes that they have witnessed.

Why is that important and how does it work in Yugabyte? What are the caveats?What are the most notable features of YugabyteDB that would lead someone to choose it over any of the myriad other options? What are the use cases that it is uniquely suited to?What are some of the systems or architecture patterns that can be replaced with Yugabyte?How does the design of Yugabyte or the different ways it is being used influence the way that users should think about modeling their data?Yugabyte is an impressive piece of engineering. Can you talk through the major design elements and how it is implemented?Easy scaling and failover is a feature that many database engines would like to be able to claim. What are the difficult elements that prevent them from implementing that capability as a standard practice? What do you have to sacrifice in order to support the level of scale and fault tolerance that you provide?Speaking of scaling, there are many ways to define that term, from vertical scaling of storage or compute, to horizontal scaling of compute, to scaling of reads and writes. What are the primary scaling factors that you focus on in Yugabyte?How do you approach testing and validation of the code given the complexity of the system that you are building?In terms of the query API you have support for a Postgres compatible SQL dialect as well as a Cassandra based syntax. What are the benefits of targeting compatibility with those platforms? What are the challenges and benefits of maintaining compatibility with those other platforms?Can you describe how the storage layer is implemented and the division between the different query formats?What are the operational characteristics of YugabyteDB? What are the complexities or edge cases that users should be aware of when planning a deployment?One of the challenges of working with large volumes of data is creating and maintaining backups. How does Yugabyte handle that problem?Most open source infrastructure projects that are backed by a business withhold various "enterprise" features such as backups and change data capture as a means of driving revenue. Can you talk through your motivation for releasing those capabilities as open source?What is the business model that you are using for YugabyteDB and how does it differ from the tribal knowledge of how open source companies generally work?What are some of the most interesting, innovative, or unexpected ways that you have seen yugabyte used?When is Yugabyte the wrong choice?What do you have planned for the future of the technical and business aspects of Yugabyte?Contact Info @karthikr on TwitterLinkedInrkarthik007 on GitHubParting Question From your perspective, what is the biggest gap in the tooling or technology for data management today?Closing Announcements Thank you for listening!
