Summary One of the perennial challenges posed by data lakes is how to keep them up to date as new data is collected. With the improvements in streaming engines it is now possible to perform all of your data integration in near real time, but it can be challenging to understand the proper processing patterns to make that performant. In this episode Ori Rafael shares his experiences from Upsolver and building scalable stream processing for integrating and analyzing data, and what the tradeoffs are when coming from a batch oriented mindset.

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

This week we are joined by AoF alumni, David Dadoun to talk about data lakes, data oceans, data puddles, and data platforms, and why so many are confused about the topic. David is a leader, professor, global speaker, and recently transitioned to an exciting new role as Head of Enterprise Data and BI at BRP in Canada.  If you feel unsure about the definition of a data lake vs a data platform, you're not alone.

Interview

Introduction How did you get involved in the area of data management? Can you describe what Ahana is and the story behind it? There has been a lot of recent activity in the Presto community. Can you give an overview of the options that are available for someone wanting to use its SQL engine for querying their data?

What is Ahana’s role in the community/ecosystem? (happy to skip this question if it’s too contentious) What are some of the notable differences that have emerged over the past couple of years between the Trino (formerly PrestoSQL) and PrestoDB projects?

Another area that has been seeing a lot of activity is data lakes and projects to make them more manageable and feature complete (e.g. Hudi, Delta Lake, Iceberg, Nessie, LakeFS, etc.). How has that influenced your product focus and capabilities?

How does this activity change the calculus for organizations who are deciding on a lake or warehouse for their data architecture?

Summary The reason that so much time and energy is spent on data integration is because of how our applications are designed. By making the software be the owner of the data that it generates, we have to go through the trouble of extracting the information to then be used elsewhere. The team at Cinchy are working to bring about a new paradigm of software architecture that puts the data as the central element. In this episode Dan DeMers, Cinchy’s CEO, explains how their concept of a "Dataware" platform eliminates the need for costly and error prone integration processes and the benefits that it can provide for transactional and analytical application design. This is a fascinating and unconventional approach to working with data, so definitely give this a listen to expand your thinking about how to build your systems.

Summary Data lake architectures have largely been biased toward batch processing workflows due to the volume of data that they are designed for. With more real-time requirements and the increasing use of streaming data there has been a struggle to merge fast, incremental updates with large, historical analysis. Vinoth Chandar helped to create the Hudi project while at Uber to address this challenge. By adding support for small, incremental inserts into large table structures, and building support for arbitrary update and delete operations the Hudi project brings the best of both worlds together. In this episode Vinoth shares the history of the project, how its architecture allows for building more frequently updated analytical queries, and the work being done to add a more polished experience to the data lake paradigm.

A revolution is occurring in data management regarding how data is collected, stored, processed, governed, managed, and provided to decision makers. The data lake is a popular approach that harnesses the power of big data and marries it with the agility of self-service. With this report, IT executives and data architects will focus on the technical aspects of building a data lake for your organization. Alex Gorelik from Facebook explains the requirements for building a successful data lake that business users can easily access whenever they have a need. You'll learn the phases of data lake maturity, common mistakes that lead to data swamps, and the importance of aligning data with your company's business strategy and gaining executive sponsorship. You'll explore: The ingredients of modern data lakes, such as the use of different ingestion methods for different data formats, and the importance of the three Vs: volume, variety, and velocity Building blocks of successful data lakes, including data ingestion, integration, persistence, data governance, and business intelligence and self-service analytics State-of-the-art data lake architectures offered by Amazon Web Services, Microsoft Azure, and Google Cloud

Summary Data lakes are gaining popularity due to their flexibility and reduced cost of storage. Along with the benefits there are some additional complexities to consider, including how to safely integrate new data sources or test out changes to existing pipelines. In order to address these challenges the team at Treeverse created LakeFS to introduce version control capabilities to your storage layer. In this episode Einat Orr and Oz Katz explain how they implemented branching and merging capabilities for object storage, best practices for how to use versioning primitives to introduce changes to your data lake, how LakeFS is architected, and how you can start using it for your own data platform.

Interview

Introduction How did you get involved in the area of data management? Can you start by giving an overview of what LakeFS is and why you built it?

There are a number of tools and platforms that support data virtualization and data versioning. How does LakeFS compare to the available options? (e.g. Alluxio, Denodo, Pachyderm, DVC, etc.)

What are the primary use cases that LakeFS enables? For someone who wants to use LakeFS what is involved in getting it set up? How is LakeFS implemented?

How has the design of the system changed or evolved since you began working on it? What assumptions did you have going into it which have since been invalidated or modified?

How does the workflow for an engineer or analyst change from working directly against S3 to running against the LakeFS interface? How do you handle merge conflicts and resolution?
