1. Login to AWS Console: Go to the AWS Management Console (https://aws.amazon.com/console/) and log in to your AWS account.
2. Navigate to DynamoDB Service: Click on the “Services” at the top left corner of the console, then select “DynamoDB” under the Database category.
3. Select the Table: From the list of DynamoDB tables, select the table for which you want to enable autoscaling.
4. Modify Table: In the table details page, click on the “Capacity” tab.
5. Enable Autoscaling: Under the “Table settings” section, find the “Auto Scaling” option and click on the “Modify” button.
6. Configure Autoscaling: In the “Auto Scaling” section, you can configure the read and write capacity settings for autoscaling. You can choose to enable autoscaling for read capacity, write capacity, or both.
7. Set Capacity Limits: Set the minimum and maximum capacity units for the read and write capacity. You can also set the target utilization percentage for autoscaling.
8. Save Changes: Once you have configured the autoscaling settings, click on the “Save” button to apply the changes.
9. Verify Autoscaling: After saving the changes, DynamoDB will start autoscaling the read and write capacity based on the configured settings.

​

1. List all the DynamoDB tables in your AWS account to identify which tables do not have autoscaling enabled:

aws dynamodb list-tables

2. For each table that does not have autoscaling enabled, update the table to enable autoscaling using the following command:

aws dynamodb update-table \
    --table-name YOUR_TABLE_NAME \
    --billing-mode PAY_PER_REQUEST \
    --provisioned-throughput ReadCapacityAutoScalingSettings={MinimumCapacity=1,MaximumCapacity=100,AutoScalingDisabled=false,TargetTrackingScalingPolicy={TargetValue=70.0,PredefinedMetricSpecification={PredefinedMetricType=DynamoDBReadCapacityUtilization}}},WriteCapacityAutoScalingSettings={MinimumCapacity=1,MaximumCapacity=100,AutoScalingDisabled=false,TargetTrackingScalingPolicy={TargetValue=70.0,PredefinedMetricSpecification={PredefinedMetricType=DynamoDBWriteCapacityUtilization}}}

3. Verify that autoscaling is enabled for the DynamoDB table by describing the table and checking the BillingMode and ProvisionedThroughput settings:

aws dynamodb describe-table --table-name YOUR_TABLE_NAME

1. Import the necessary libraries:

import boto3

2. Initialize the DynamoDB client:

dynamodb = boto3.client('dynamodb')

3. List all the DynamoDB tables:

response = dynamodb.list_tables()
tables = response['TableNames']

4. Enable autoscaling for each table:

for table_name in tables:
    response = dynamodb.update_table(
        TableName=table_name,
        ProvisionedThroughput={
            'ReadCapacityUnits': 5,  # Set your desired read capacity units
            'WriteCapacityUnits': 5  # Set your desired write capacity units
        },
        BillingMode='PROVISIONED',  # Set the billing mode to PROVISIONED
        GlobalSecondaryIndexUpdates=[
            {
                'Update': {
                    'IndexName': 'string',
                    'ProvisionedThroughput': {
                        'ReadCapacityUnits': 5,  # Set your desired read capacity units
                        'WriteCapacityUnits': 5  # Set your desired write capacity units
                    }
                }
            },
        ],
        StreamSpecification={
            'StreamEnabled': False
        },
        SSESpecification={
            'Enabled': False
        },
        TimeToLiveSpecification={
            'Enabled': False
        },
        BillingMode='PAY_PER_REQUEST'  # Set the billing mode to PAY_PER_REQUEST for autoscaling
    )

5. Replace the placeholder values like 'ReadCapacityUnits': 5 and 'WriteCapacityUnits': 5 with your desired values for read and write capacity units.
6. Run the Python script to enable autoscaling for all DynamoDB tables.
