Posted on: Jul 10, 2026

Amazon DocumentDB (with MongoDB compatibility) now supports R8g.24xlarge and R8g.48xlarge database instances. R8g instances are powered by AWS Graviton4 processors and feature DDR5 memory, enabling customers to achieve higher throughput and support larger working sets in memory. With R8g.24xlarge (96 vCPUs, 768 GiB memory) and R8g.48xlarge (192 vCPUs, 1,536 GiB memory), customers can run more demanding workloads such as high-concurrency transactional applications, large-scale document processing, and memory-intensive operational workloads.

Customers can get started with R8g.24xlarge and R8g.48xlarge instances through the AWS Management Console, CLI, and SDK by modifying their existing Amazon DocumentDB database cluster or creating a new one. R8g instances are available for Amazon DocumentDB 5.0+ on both Standard and IO-Optimized cluster storage configurations.
