This is where you define your primary key, including a HASH key and an optional RANGE key. You'll then need to provide the KeySchema of your table. You only need to define attributes which are used in your primary key or are used in secondary indexes. For us, this means we have an attribute with the name 'Username' and of type 'S', for String. An attribute definition includes the name and type of the attribute.

When creating a table, you will need to provide AttributeDefinitions for each attribute you need to define. We want to create a table to hold Users that will use a simple primary key of 'Username', which is a string. The first step is to create our table that we'll use throughout this example. Note that I'm appending a $LOCAL variable to the end of every command to facilitate those using DynamoDB Local. To follow along with the examples in this lesson, make sure you have your environment set up properly. Then we'll move on to updating and deleting items in the following lesson. The next lesson will explain using expressions in these API calls for advanced functionality. This lesson will only cover the basics of using these API calls. Then, we'll explore two basic API calls: PutItem and GetItem. We'll create a Users table with a simple primary key of Username. In this lesson, we're going to learn the basics of inserting and retrieving items with DynamoDB. Items are the key building block in DynamoDB.
