Creating a DynamoDB Table

In this hands-on lab, we will create a DynamoDB table to store pet inventory data. In the scenario, the data architect on the team has requested a table definition with a partition key of `pet_species` with the data type `String`, a sort key of `pet_id` with the data type `Number`, and that the table be named `PetInventory`. Because the workload in development is not known, `On-Demand` provisioning should be utilized. We're free to create the table with any method we choose (web console, CLI/SDK, CloudFormation).

aws dynamodb
    create-table
        --table-name PetInventory
        --attribute-definitions
            AttributeName=pet_species,AttributeType=S
            AttributeName=pet_id,AttributeType=N
        --key-schema
            AttributeName=pet_species,KeyType=HASH
            AttributeName=pet_id,KeyType=RANGE
        --billing-mode PAY_PER_REQUEST

Challenge

Create a DynamoDB Table with the Python Boto3 SDK

The following Python script will create the requested DynamoDB table:

import boto3
ddb = boto3.client('dynamodb')
createResponse = ddb.create_table(
    AttributeDefinitions=[
        {
            'AttributeName':'pet_species',
            'AttributeType': 'S',
        }, 
        {
            'AttributeName':'pet_id',
            'AttributeType':'N'
        }
    ], 
    KeySchema=[
        {
            'AttributeName':'pet_species',
            'KeyType':'HASH'
        },
        {
            'AttributeName':'pet_id',
            'KeyType':'RANGE'
        },
    ],
    BillingMode = 'PAY_PER_REQUEST',
    TableName='PetInventory'
)
