# Amazon EMR 7.5 Boosts Apache Spark and Iceberg Performance, Delivering 3.6x Faster Workload Execution Compared to Spark 3.5.3 and Iceberg 1.6.1

Amazon Elastic MapReduce (EMR) has long been a cornerstone for organizations seeking scalable, cost-effective big data processing in the cloud. With the release of **Amazon EMR 7.5**, Amazon Web Services (AWS) has introduced significant performance enhancements for **Apache Spark** and **Apache Iceberg**, two of the most widely used open-source frameworks for big data analytics. According to AWS, workloads running on EMR 7.5 can execute up to **3.6x faster** compared to Spark 3.5.3 and Iceberg 1.6.1, making it a game-changer for data-intensive applications.

This article explores the key improvements in Amazon EMR 7.5, the technical advancements behind the performance boost, and the implications for businesses leveraging big data analytics.

## **What is Amazon EMR?**

Amazon EMR is a managed service that simplifies the deployment and scaling of big data frameworks like Apache Hadoop, Apache Spark, and Presto. It enables organizations to process vast amounts of data quickly and cost-effectively by leveraging the elasticity of AWS cloud infrastructure. EMR is widely used for use cases such as data transformation, machine learning, real-time analytics, and large-scale data querying.

## **Key Highlights of Amazon EMR 7.5**

The latest release of Amazon EMR, version 7.5, focuses on optimizing the performance of Apache Spark and Apache Iceberg, two critical components for modern data processing and analytics.

### **1. Enhanced Apache Spark Performance**
Apache Spark is a distributed data processing engine known for its speed and ease of use. EMR 7.5 introduces several optimizations to Spark, including:

– **Improved Query Execution:** EMR 7.5 incorporates advanced query planning and execution optimizations, reducing the time required to process complex queries.
– **Dynamic Resource Allocation:** Enhanced resource management ensures that Spark jobs utilize cluster resources more efficiently, minimizing idle time and improving throughput.
– **Optimized Shuffle Operations:** The shuffle phase, a common bottleneck in distributed data processing, has been significantly improved, leading to faster data movement between nodes.

These enhancements collectively contribute to a **3.6x performance improvement** for Spark workloads compared to Spark 3.5.3.

### **2. Apache Iceberg Integration**
Apache Iceberg is an open table format designed for managing large-scale datasets in data lakes. It provides features like schema evolution, time travel, and ACID transactions, making it a popular choice for modern data lake architectures.

In EMR 7.5, Iceberg performance has been optimized through:

– **Faster Metadata Operations:** Iceberg’s metadata management has been streamlined, reducing the overhead associated with querying large datasets.
