# AWS raises EMR Serverless shuffle limit from 200 GB to 1TB

_Published Friday, October 2, 2026 at 9:08 PM EDT · Infrastructure, Products · Latest · Tier 2 — Notable_

AWS says Amazon EMR Serverless now supports up to 1TB of shuffle operations, raising its previous 200 GB per-job limit. The change expands capacity for Apache Spark jobs that move data between processing tasks during joins, aggregations and sorting.

The enhancement also adds spill support, which moves data to disk when memory-intensive operations need it. AWS says the feature is available with Amazon emr-7.14, emr-spark-8.1 and later in 18 AWS Regions where EMR Serverless operates.
