DynamoDB STREAMS & Lambda Triggers | .NET ON AWS | AWS Serverless | Amazon

DynamoDB Streams capture a time-ordered sequence of events in any DynamoDB table. It is also referred to as Change Data Capture. Whenever an application creates, updates, or deletes items in the table, DynamoDB Streams writes a stream record with the primary key attributes of the items that were modified. A *stream record* contains information about a data modification to a single item in a DynamoDB table.

DynamoDB streams help decouple core application logic from the effects that happen afterward. It helps with scenarios where you want to replicate data, generate read models of your data, etc. It can also be used as an alternative for Transactions when you need to update across multiple sources.

In this video, we will learn how to get started with DynamoDB streams and use Lambda functions using .NET to handle stream events. We will also look at the different configurations associated with the Lambda Triggers, handle exceptions, and different patterns of integrating with DynamoDB stream events.
