Summary The best way to make sure that you don’t leak sensitive data is to never have it in the first place. The team at Skyflow decided that the second best way is to build a storage system dedicated to securely managing your sensitive information and making it easy to integrate with your applications and data systems. In this episode Sean Falconer explains the idea of a data privacy vault and how this new architectural element can drastically reduce the potential for making a mistake with how you manage regulated or personally identifiable information.

Interview

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?

What do you see as the closest alternatives? What are the core differentiators that might lead someone to choose Flyte over e.g. Airflow/Prefect/Dagster?

What are the core primitives that Flyte exposes for building up complex workflows?

Machine learning use cases have been a core focus since the project’s inception. What are some of the ways that that manifests in the design and feature set?

Can you describe the architecture of Flyte?

How have the design and goals of the platform changed/evolved since you first started working on it?

What are the changes in the data ecosystem that have had the most substantial impact on the Flyte project? (e.g. roadmap, integrations, pushing people toward adoption, etc.) What is the process for setting up a Flyte deployment? What are the user personas that you prioritize in the design and feature development for Flyte? What is the workflow for someone building a new pipeline in Flyte?

What are the patterns that you and the community have established to encourage discovery and reuse of granular task definitions? Beyond code reuse, how can teams scale usage of Flyte at the company/organization level?

What are the affordances that you have created to facilitate local development and testing of workflows while ensuring a smooth transition to production?

What are the patterns that are available for CI/CD of workflows using Flyte?

How have you approached the design of data contracts/type definitions to provide a consistent/portable API for defining inter-task dependencies across languages? What are the available interfaces for extending Flyte and building integrations with other components across the data ecosystem? Data orchestration engines are a natural point for generating and taking advantage of rich metadata. How do you manage creation and propagation of metadata within and across the framework boundaries? Last year you founded Union to offer a managed version of Flyte. What are the features that you are offering beyond what is available in the open source?

What are the opportunities that you see for the Flyte ecosystem with a corporate entity to invest in expanding adoption?

Summary At the foundational layer many databases and data processing engines rely on key/value storage for managing the layout of information on the disk. RocksDB is one of the most popular choices for this component and has been incorporated into popular systems such as ksqlDB. As these systems are scaled to larger volumes of data and higher throughputs the RocksDB engine can become a bottleneck for performance. In this episode Adi Gelvan shares the work that he and his team at SpeeDB have put into building a drop-in replacement for RocksDB that eliminates that bottleneck. He explains how they redesigned the core algorithms and storage management features to deliver ten times faster throughput, how the lower latencies work to reduce the burden on platform engineers, and how they are working toward an open source offering so that you can try it yourself with no friction.

Summary Data quality control is a requirement for being able to trust the various reports and machine learning models that are relying on the information that you curate. Rules based systems are useful for validating known requirements, but with the scale and complexity of data in modern organizations it is impractical, and often impossible, to manually create rules for all potential errors. The team at Anomalo are building a machine learning powered platform for identifying and alerting on anomalous and invalid changes in your data so that you aren’t flying blind. In this episode founders Elliot Shmukler and Jeremy Stanley explain how they have architected the system to work with your data warehouse and let you know about the critical issues hiding in your data without overwhelming you with alerts.

Summary Communication and shared context are the hardest part of any data system. In recent years the focus has been on data catalogs as the means for documenting data assets, but those introduce a secondary system of record in order to find the necessary information. In this episode Emily Riederer shares her work to create a controlled vocabulary for managing the semantic elements of the data managed by her team and encoding it in the schema definitions in her data warehouse. She also explains how she created the dbtplyr package to simplify the work of creating and enforcing your own controlled vocabularies.

Interview

Introduction How did you get involved in the area of data management? Can you start by giving a brief recap of the principles of the data mesh and the story behind it? How has your view of the principles of the data mesh changed since our conversation in July of 2019? What are some of the ways that your work on the data mesh book influenced your thinking on the practical elements of implementing a data mesh? What do you view as the as-yet-unknown elements of the technical and social design constructs that are needed for a sustainable data mesh implementation? In the opening of your book you state that "Data Mesh is a new approach in sourcing, managing, and accessing data for analytical use cases at scale". As with everything, scale is subjective, but what are some of the heuristics that you rely on for determining when a data mesh is an appropriate solution? What are some of the ways that data mesh concepts manifest at the boundaries of organizations? While the idea of federated access to data product quanta reduces the amount of coordination necessary at the organizational level, it raises the spectre of more complex logic required for consumers of multiple quanta. How can data mesh implementations mitigate the impact of this problem? What are some of the technical components that you have found to be best suited to the implementation of data elements within a mesh? What are the technological components that are still missing for a mesh-native data platform? How should an organization that wishes to implement a mesh style architecture think about the roles and skills that they will need on staff?

How can vendors factor into the solution?

What is the role of application developers in a data mesh ecosystem and how do they need to change their thinking around the interfaces that they provide in their products? What are the most interesting, innovative, or unexpected ways that you have seen data mesh principles used? What are the most interesting, unexpected, or challenging lessons that you have learned while working on data mesh implementations? When is a data mesh the wrong approach? What do you think the future of the data mesh will look like?

Interview

Introduction How did you get involved in the area of data management? Can you start by giving an overview of the state of the market for data lakes today?

What are the prevailing architectural and technological patterns that are being used to manage these systems?

Batch and streaming systems have been used in various combinations since the early days of Hadoop. The Lambda architecture has largely been abandoned, so what is the answer for today’s data lakes? What are the challenges presented by streaming approaches to data transformations?

The batch model for processing is intuitive despite its latency problems. What are the benefits that it provides?

The core concept for data orchestration is the DAG. How does that manifest in a streaming context? In batch processing idempotent/immutable datasets are created by re-running the entire pipeline when logic changes need to be made. Given that there is no definitive start or end of a stream, what are the options for amending logical errors in transformations? What are some of the da

Summary The most important gauge of success for a data platform is the level of trust in the accuracy of the information that it provides. In order to build and maintain that trust it is necessary to invest in defining, monitoring, and enforcing data quality metrics. In this episode Michael Harper advocates for proactive data quality and starting with the source, rather than being reactive and having to work backwards from when a problem is found.

Interview

Introduction How did you get involved in the area of data management? What is your definition for the term "data quality" and what are the implied goals that it embodies?

What are some ways that different stakeholders and participants in the data lifecycle might disagree about the definitions and manifestations of data quality?

The market for "data quality tools" has been growing and gaining attention recently. How would you categorize the different approaches taken by open source and commercial options in the ecosystem?

What are the tradeoffs that you see in each approach? (e.g. data warehouse as a chokepoint vs quality checks on extract)

What are the difficulties that engineers and stakeholders encounter when identifying and defining information that is necessary to identify issues in their workflows? Can you describe some examples of adding data quality checks to the beginning stages of a data workflow and the kinds of issues that can be identified?

What are some ways that quality and observability metrics can be aggregated across multiple pipeline stages to identify more complex issues?

Interview

Introduction How did you get involved in the area of data management? Can you describe what ClicData is and the story behind it? How would you characterize the current state of the market for business intelligence?

What are the systems/capabilities that are required to run a full-featured BI system?

What are the challenges that businesses face in developing in-house capacity for business intelligence? Can you describe how the ClicData platform is architected?

How has it changed or evolved since you first began working on it?

How are you approaching schema design and evolution in the storage layer? How do you handle questions of data security/privacy/regulations given that you are storing the information on behalf of the business? In your work with clients what are some of the challenges that businesses are facing when attempting to answer questions and gain insights from their data in a rep

Summary The perennial question of data warehousing is how to model the information that you are storing. This has given rise to methods as varied as star and snowflake schemas, data vault modeling, and wide tables. The challenge with many of those approaches is that they are optimized for answering known questions but brittle and cumbersome when exploring unknowns. In this episode Ahmed Elsamadisi shares his journey to find a more flexible and universal data model in the form of the "activity schema" that is powering the Narrator platform, and how it has allowed his customers to perform self-service exploration of their business domains without being blocked by schema evolution in the data warehouse. This is a fascinating exploration of what can be done when you challenge your assumptions about what is possible.

Interview

Introduction How did you get involved in the area of data management? Can you describe what Narrator is and the story behind it? What are the challenges that you have seen organizations encounter when attempting to make analytics a self-serve capability? What are the use cases that you are focused on? How does Narrator fit within the data workflows of an organization? How is the Narrator platform implemented?

How has the design and focus of the technology evolved since you first started working on Narrator?

The core element of the analyses that you are building is the "activity schema". Can you describe the design process that led you to that format?

What are the challenges that are posed by more widely used modeling techniques such as star/s

Summary The market for business intelligence has been going through an evolutionary shift in recent years. One of the driving forces for that change has been the rise of analytics engineering powered by dbt. Lightdash has fully embraced that shift by building an entire open source business intelligence framework that is powered by dbt models. In this episode Oliver Laslett describes why dashboards aren’t sufficient for business analytics, how Lightdash promotes the work that you are already doing in your data warehouse modeling with dbt, and how they are focusing on bridging the divide between data teams and business teams and the requirements that they have for data workflows.
