AWS DynamoDB PAGINATION | .NET ON AWS | AWS Serverless | Amazon

Hey 👋 DynamoDB charges for reading, writing, and storing data in your DynamoDB tables. As a rule of thumb, when querying data, you can consider that each record that you retrieve from the database has a direct cost attached to it.

So using pagination and limiting the records you retrieve for your application and users has a direct impact on saving cost and also performance.

In this video, let’s learn how to implement pagination when querying and retrieving data from DynamoDB. We will look at the code examples using .NET, but the concepts apply to other programming languages as well. We will learn how to use the LastEvaluatedKey, ExclusiveStartKey, Limit, and ScanIndexForward properties to page data when building APIs.

This video is sponsored by AWS and is part of my .NET on AWS Series.
