- Scale up your DynamoDB table when the consumed writes 90% of the total provisioned writes
- Scale up your reads with 50%
- Scale up your writes with 40%
- Scale down your DynamoDB table when the consumed reads 30% of the total provisioned reads
- Scale down your DynamoDB table when the consumed writes 40% of the total provisioned writes
- Scale down your reads with 40%
- Scale down your writes with 70%
- Check for changes every 5 minutes
