MDS Newsletter #77

Ayushi Rathod -

In this week's newsletter, learn the steps to use Docker Compose to integrate Kafka and S3 with Spark Structured Streaming and read how to apply the principles of chaos engineering to data engineering! And be sure to register for two fantastic data events taking place over the next few weeks!

Modern Data Show S02 E04

S02 E04: Legacy to Modern: Transforming Analytics Infrastructure with Ian Macomber, Head of Analytics Engineering & Data Science at Ramp: In this episode of Modern Data Show Ian Macomber discussed the company's approach to automating finance tools and building the next generation of finance through data-driven decision-making. Macomber emphasizes the importance of cross-functional collaboration and embedding the data team into every part of the product engineering process. He also highlights the need for data compliance and privacy to be invested in every day and not treated as a one-time effort. Macomber warns against "Layerinitis," where teams prioritize quick solutions over long-term effects, and advises celebrating the hardening of code and inviting people into codebases to teach them best practices.

Good reads and resources

  • Dockerizing Spark Structured Streaming with Kafka And LocalStack: This article is written by Tal Wanish who explains how to integrate Kafka and S3 with Spark Structured Streaming using Docker Compose, to create a simple Spark application that aggregates data from a Kafka topic and writes it to a Delta table on S3. He divides the article into three parts - coding the Spark application along with its integration test, Dockerizing the application, and Dockerizing its dependencies (Kafka and LocalStack). He assumes some familiarity with Spark Structured Streaming API, Docker, Scala, and dbt and provides a step-by-step guide on how to Dockerize the application and its dependencies to create an isolated environment for local development that fully integrates Spark, Kafka, and S3. He also provides the complete source code in the repository for extended study.
  • The Chaos Data Engineering Manifesto: Spare The Rod, Spoil Prod: This article is written by Shane Murray who discusses how the New York Times recently conducted a "premortem" exercise, intentionally introducing points of failure within its systems to test thresholds and improve resilience. The exercise was based on the concept of chaos engineering, which involves deliberately causing failure within a system to better understand its limits and strengthen it. While chaos engineering is not a common practice within data engineering, Shane suggests that data teams need to focus on building and maintaining reliable data systems at scale. He proposes applying the principles of chaos engineering to data engineering to improve data observability and ensure critical operations are not compromised. It involves having a bias for production but minimizing the blast radius, understanding it is never a perfect time to test data, formulating hypotheses, identifying variables at the system, code and data levels, bringing everyone into one room, and making it a regular occurrence. The laws are designed to stress test data systems and to help teams to better understand and prevent data incidents.
