with Amazon DynamoDB
In this tutorial, you will learn how to create a simple table, add data, scan and query the data, delete data, and delete the table by using the DynamoDB console. DynamoDB is a fully managed NoSQL database that supports both document and key-value store models. Its flexible data model, reliable performance, and automatic scaling of throughput capacity make it a great fit for mobile, web, gaming, ad tech, IoT, and many other applications.
Manage Your AWS Resources
Sign in to the ConsoleOpen the AWS Management Console so that you can keep this step-by-step guide open. When this screen loads, begin typing DynamoDB in the search bar and choose to open the DynamoDB console.
In this step, you will use the DynamoDB console to create a table.
e. Next, you will enable DynamoDB auto scaling for your table.
DynamoDB auto scaling will change the read and write capacity of your table based on request volume. Using an AWS Identity and Access Management (AWS IAM) role called DynamoDBAutoscaleRole, DynamoDB will manage the auto scaling process on your behalf. DynamoDB creates this role for you the first time you enable auto scaling in an account.
Instruct DynamoDB to create the role by clearing the Use default settings check box.
f. Scroll down the screen past Secondary indexes, Provisioned capacity, and Auto Scaling to the Create button. We won't change these settings for the tutorial.
In the Auto Scaling section, notice that DynamoDB will create the DynamoDBAutoscaleRole role for you.
Now
When the Music table is ready to use, it appears in the table list with a
Congratulations! You have created a NoSQL table using the DynamoDB console.
In this step, you will add data to your new DynamoDB table.
In this step, you will search for data in the table using query operations. In DynamoDB, query operations are efficient and use keys to find data. Scan operations traverse the entire table.
b. You can use the console to query the Music table in various ways. For your first query, do the following:
- In the Artist box, type No One You Know, and choose Start search. All songs performed by No One You Know are displayed.
Try another query:
- In the Artist box, type The Acme Band, and choose Start search. All songs performed by The Acme Band are displayed.
In this step, you will delete an item from your DynamoDB table.
In this step, you will delete your DynamoDB table.
a. You can easily delete a table from the DynamoDB console. It is a best practice to delete tables you are no longer using so that you don’t keep getting charged for them.
- In the DynamoDB console, choose the option next to the Music table and then choose Delete table.
- In the confirmation dialog box, choose Delete.
You have created your first DynamoDB table, added items to your table, and then queried the table to find the items you wanted. You also learned how to visually manage your DynamoDB tables and items through the AWS Management Console.
DynamoDB is a great fit for mobile, web, gaming, ad tech, and IoT applications where scalability, throughput, and reliable performance are key considerations.
Now that you have learned how to create, manage, and query tables and items from the AWS Management Console, you can progress to the next tutorial where you will learn how to import large amounts of data and easily find the information you need. You’ll import a movie database to see how you can quickly find details about your favorite actors and characters.
