Amazon SageMaker Unified Studio Notebooks now support Amazon EMR Serverless with Apache Spark Connect, giving data engineers and analysts more flexibility in choosing their Spark runtime for interactive analytics and data engineering workloads. In addition to Amazon Athena Spark, users can now leverage Amazon EMR Serverless as their Spark runtime, selecting the optimal engine based on their requirements. With this launch, you can run PySpark and Spark SQL on an EMR Serverless Spark Application in Notebook cells. Users can select their Spark runtime from the Notebook side panel, and the selecte

Why this matters
Why now

The continuous evolution of cloud data processing and AI/ML development platforms (like SageMaker) necessitates integration with diverse and scalable backend compute options.

Why it’s important

This development improves flexibility and cost-efficiency for data professionals and developers who need to run large-scale analytics and data engineering workloads within a unified environment.

What changes

Users of Amazon SageMaker Unified Studio Notebooks can now directly utilize EMR Serverless for Apache Spark workloads, expanding their choices beyond Athena Spark.
