Create table in DynamoDB

var params = {
    TableName: 'todos',
    KeySchema: [{ AttributeName: 'uuid', KeyType: 'HASH' }],
    AttributeDefinitions: [{  AttributeName: 'uuid', AttributeType: 'S', }],
    ProvisionedThroughput: { ReadCapacityUnits: 1, WriteCapacityUnits: 1, }
};

dynamodb.createTable(params, function(err, data) {
    if (err) ppJson(err);
    else ppJson(data);
});

aws dynamodb create-table --table-name todos \
                          --attribute-definitions AttributeName=subject,AttributeType=S \
                          --key-schema AttributeName=subject,KeyType=HASH \
                          --provisioned-throughput ReadCapacityUnits=1,WriteCapacityUnits=1

Delete table in DynamoDB
