Amazon EMR launches new capabilities to enhance EMR on EC2 cluster scaling experience

We are excited to announce that Amazon EMR has launched two new capabilities that enhances the scaling experience for Amazon EMR on EC2 clusters: a new retry mechanism for faster scaling of your Amazon EMR on EC2 clusters running Presto or Trino; and faster scale-down of Amazon EMR on EC2 clusters by enforcing the data redundancy requirements. These capabilities are automatically enabled for clusters running Amazon EMR 6.12 or higher releases and no action is needed from your end.
