This blog post explains how to set up Change Data Capture (CDC) from an AWS DynamoDB database to a SingleStore database using DynamoDB streams and a Lambda function. The process involves five steps: enabling DynamoDB streams, setting up the SingleStore database, creating a Lambda function to consume the stream and write to SingleStore, connecting the DynamoDB stream to the Lambda function, and testing out the connection from DynamoDB to SingleStore by inserting, updating, and deleting data in DynamoDB and verifying that it flows through to SingleStore. The blog post provides examples of Python scripts for each step, including generating synthetic transaction data, writing it to DynamoDB, and then reading it back into SingleStore. It also notes the importance of using persisted computed columns in SingleStore to parse out individual key-value pairs from JSON blobs.
