Data Engineering Podcast

Summary The information about how data is acquired and processed is often as important as the data itself. For this reason metadata management systems are built to track the journey of your business data to aid in analysis, presentation, and compliance. These systems are frequently cumbersome and difficult to maintain, so Octopai was founded to alleviate that burden. In this episode Amnon Drori, CEO and co-founder of Octopai, discusses the business problems he witnessed that led him to starting the company, how their systems are able to provide valuable tools and insights, and the direction that their product will be taking in the future.

Your host is Tobias Macey and today I’m interviewing Christopher Bergh about DataKitchen and the rise of DataOps Interview Introduction How did you get involved in the area of data management? How do you define DataOps? How does it compare to the practices encouraged by the DevOps movement? How does it relate to or influence the role of a data engineer? How does a DataOps oriented workflow differ from other existing approaches for building data platforms? One of the aspects of DataOps that you call out is the practice of providing multiple environments to provide a platform for testing the various aspects of the analytics workflow in a non-production context. What are some of the techniques that are available for managing data in appropriate volumes across those deployments? The practice of testing logic as code is fairly well understood and has a large set of existing tools. What have you found to be some of the most effective methods for testing data as it flows through a system? One of the practices of DevOps is to create feedback loops that can be used to ensure that business needs are being met. What are the metrics that you track in your platform to define the value that is being created and how the various steps in the workflow are proceeding toward that goal? In order to keep feedback loops fast it is necessary for tests to run quickly. How do you balance the need for larger quantities of data to be used for verifying scalability/performance against optimizing for cost and speed in non-production environments? How does the DataKitchen platform simplify the process of operationalizing a data analytics workflow? As the need for rapid iteration and deployment of systems to capture, store, process, and analyze data becomes more prevalent how do you foresee that feeding back into the ways that the landscape of data tools are designed and developed?

Your host is Tobias Macey and today I’m interviewing Roger Chen about data liquidity and its impact on our future economies Interview Introduction How did you get involved in the area of data management? You wrote an essay discussing how the increasing usage of machine learning and artificial intelligence applications will result in a demand for data that necessitates what you refer to as ‘Data Liquidity’. Can you explain what you mean by that term? What are some examples of the types of data that you envision as being foundational to multiple organizations and problem domains? Can you provide some examples of the structures that could be created to facilitate data sharing across organizational boundaries? Many companies view their data as a strategic asset and are therefore loathe to provide access to other individuals or organizations. What encouragement can you provide that would convince them to externalize any of that information? What kinds of storage and transmission infrastructure and tooling are necessary to allow for wider distribution of, and collaboration on, data assets? What do you view as being the privacy implications from creating and sharing these larger pools of data inventory? What do you view as some of the technical challenges associated with identifying and separating shared data from those that are specific to the business model of the organization? With broader access to large data sets, how do you anticipate that impacting the types of businesses or products that are possible for smaller organizations?
