Read Data in a DynamoDB Table

DynamoDB is a NoSQL database service provided by AWS. In this lab, we’ll learn to read data from a DynamoDB table.

We can read data from an existing table in two ways:

• Querying returns the partition of data specified by the partition key and sorted according to the sort key.
• Scanning applies filters to the table data and returns the filtered items.

We’ll cover both approaches in this lab.

Lab tasks

• Create a table.
• Add data to the table.
• Query the table.
• Scan the table.
• Clean up.
