DynamoDB tables should automatically scale capacity with demand
Checks that the DynamoDB table uses on-demand capacity mode, or provisioned mode with auto scaling configured. A table whose capacity follows demand avoids the throttling exceptions a fixed provisioned capacity returns at a traffic peak, which keeps the applications that use it available.

How to fix it
In the console
DynamoDB → Tables → the table → Additional settings → Read/write capacity
- Capacity mode
- On-demand, or Provisioned with auto scaling on for both read and write capacity
- Read capacity: Auto scaling
- On, if Provisioned, with minimum and maximum capacity units and a target utilization
- Write capacity: Auto scaling
- On, if Provisioned, set as for read capacity
With the AWS CLI
aws dynamodb update-table --table-name <table-name> --billing-mode PAY_PER_REQUEST --region <region>With Terraform
resource "aws_dynamodb_table" "this" {
name = var.table_name
billing_mode = "PAY_PER_REQUEST"
