In the last post, we looked at Spark’s architecture. Now, let’s talk about how you actually write code for it. Neylson Crepalde highlights two main ways to interact with Spark: the DataFrame API and Spark SQL.
If there is one tool that defined the “Big Data” era, it’s Apache Spark. It’s the engine that handles everything from terabyte-scale ETL to complex machine learning. In Chapter 5, Neylson Crepalde breaks down exactly how Spark works and why it’s so powerful on Kubernetes.
We’ve talked about the architecture, but what about the actual tools? To build a modern data lakehouse on Kubernetes, you need a specific set of tools that can handle scale, automation, and speed.
We’ve all heard the terms “Data Warehouse” and “Data Lake,” but do you actually know why we keep switching between them? In Chapter 4 of Big Data on Kubernetes, Neylson Crepalde gives a masterclass on how data architecture has evolved to keep up with the modern world.
Testing things locally with Kind is great, but big data usually needs big iron. In this part of the hands-on journey, Neylson Crepalde shows us how to scale up to a managed cloud environment.
Reading about architecture is one thing, but actually seeing a cluster run is where it sticks. In the third chapter of Big Data on Kubernetes, Neylson Crepalde moves from theory to practice.
In the last post, we talked about the “brain and muscles” of a Kubernetes cluster. But how do we actually tell that brain what to do? We use Objects.
If you want to run big data workloads on Kubernetes, you have to understand how the system is actually put together. It’s not just “magic magic cloud stuff”—it’s a carefully coordinated cluster of machines.
In my last post, we talked about why containers are the bedrock of modern data engineering. But honestly, just running other people’s images only gets you so far. The real magic happens when you start packaging your own custom code.
If you are working with data today, you can’t really ignore containers. They have become the standardized unit for how we develop, ship, and deploy software. But why do we care so much about them in the big data world?
We are living in a world where data is basically everywhere. From your phone to social media and every single online purchase, the amount of info we generate is staggering. But here’s the thing: just having data isn’t enough. You have to be able to process it, and that’s where things get complicated.
