Amazon DocumentDB (with MongoDB compatibility) is a fast, scalable, highly available, and fully managed document database service that supports MongoDB workloads. Amazon DocumentDB makes it easy and intuitive to store, query, and index JSON data.

Amazon DocumentDB now supports r5.8xlarge and r5.16xlarge instances in addition to existing R5 instances, which offer more granular creation and scaling options within R5 instance types.

R5 instances are the latest generation of memory optimized instances that deliver 5% additional memory per vCPU and up to 20% increased CPU performance over R4 instances. DocumentDB R5 instances provide up to 100% better performance over R4 instance for the same instance cost. For more information, see Amazon DocumentDB pricing page, and optimizing for cost with Amazon DocumentDB.

You can easily create a new r5.8xlarge and r5.16xlarge, or modify your existing Amazon DocumentDB clusters to scale to these new R5 instances in the Amazon DocumentDB Management Console. Please refer to the Amazon DocumentDB documentation for more information.
