Apache Spark 4.0 is a major update, bringing new APIs, performance improvements, and a more modular design. Here's a summary of what's new and why it matters. In this post, we’ll look at the most exciting new features in Apache Spark 4.0, what they m...
In software engineering, choosing a system architecture is an essential decision that can affect the entire life-cycle of an application, from development and testing to deployment, maintenance, and debugging. There are two main architectures: Monoli...
One of the most important decisions in your Apache Spark pipeline is how you store your data. The data format you choose can dramatically affect performance, storage costs, and query speed. Let’s explore the most common file formats supported by Apac...
Apache Spark has been a popular choice for large-scale distributed data processing. However, as data teams move to cloud architectures and separate computes from client interfaces, the traditional tightly coupled Spark driver model has begun to revea...
Apache Spark SQL uses SQL capabilities to process large-scale structured data. One powerful feature in modern SQL is the WITH clause, supported in Spark SQL as Common Table Expressions (CTE). CTE offer a more organized, readable, and often more effic...
When working with large datasets in Apache Spark, a common performance issue is data skew. This occurs when a few keys dominate the data distribution, leading to uneven partitions and slow queries. It mainly happens during operations that require shu...
