Question: How do I create an id in DynamoDB?

Answer

In DynamoDB, you can create a unique identifier (ID) for each item in a table using a primary key. A primary key is a unique identifier used to identify each item in a table, consisting of one or two attributes.

There are two types of primary keys in DynamoDB:

1. Partition key: A simple primary key composed of one attribute known as the partition key.
2. Partition key and sort key: Also known as a composite primary key, composed of two attributes. The first attribute is the partition key, and the second is the sort key.

When you create a table, you need to specify the primary key attributes. The primary key attributes determine the uniqueness of each item in the table and define the items' partition and sort order.
