Enable DynamoDB Table Auto Scaling Rule

DynamoDB Table Auto Scaling for FFIEC Compliance

Description

Troubleshooting

2. 1.
   Check the status of auto scaling for the DynamoDB table.
4. 2.
   Ensure that the correct policies and permissions are in place for enabling auto scaling.
6. 3.
   Verify that the table has appropriate read and write capacity provisioned.
8. 4.
   Review the CloudWatch alarms associated with the table to identify any scaling issues.
10. 5.
    Check for any errors or warnings in the CloudTrail logs related to auto scaling.

Implementation

2. 1.
   Identify the DynamoDB table that needs to have auto scaling enabled.
4. 2.
   Open the AWS Management Console and navigate to the DynamoDB service.
6. 3.
   Select the desired table from the list of tables.
8. 4.
   Click on the "Capacity" tab in the table details.
10. 5.
    Under "Auto Scaling", click on the "Manage capacity" button.
12. 6.
    On the "Auto scaling" configuration page, click on "Add autoscaling" to create a new auto scaling policy.
14. 7.
    Configure the auto scaling policy based on the desired criteria, such as minimum and maximum capacity units, target utilization, and scaling metrics.
16. 8.
    Click on "Save" to apply the auto scaling policy to the table.

Example

import boto3

# Create a DynamoDB client
dynamodb_client = boto3.client('dynamodb')

# Enable auto scaling for a table
response = dynamodb_client.update_table(
    TableName='ffiec_table',
    ProvisionedThroughput={
        'ReadCapacityUnits': 10,   # Set the initial read capacity
        'WriteCapacityUnits': 5    # Set the initial write capacity
    },
    BillingMode='PROVISIONED',
    # Configure auto scaling
    StreamSpecification={
        'StreamEnabled': False     # Optional, depends on your requirement
    },
    SSESpecification={
        'Enabled': False           # Optional, depends on your requirement
    },
    # Add any desired extra configuration here
    # ...
    # Enable auto scaling
    GlobalSecondaryIndexUpdates=[
        {
            'Update': {
                'IndexName': 'index_name',
                'ProvisionedThroughput': {
                    'ReadCapacityUnits': 10,
                    'WriteCapacityUnits': 5
                }
            }
        }
    ],
    # ...
    # Additional parameters as needed, based on your configuration
)

print(response)
