Specify autoscaling of dynamodb with boto3 client

Solution 1:

Here is the documentation for autoscaling,

http://boto3.readthedocs.io/en/latest/reference/services/application-autoscaling.html

You need to use the namespace 'dynamodb' to autoscale dynamodb.

You can also do via cli it will also give you an idea on parameters,

aws application-autoscaling register-scalable-target \
    --service-namespace dynamodb \
    --resource-id "table/TestTable" \
    --scalable-dimension "dynamodb:table:WriteCapacityUnits" \
    --min-capacity 5 \
    --max-capacity 10 \
    --role-arn roleARN
