Amazon DynamoDB Immersion Day > LCDC: Change Data Capture for Amazon DynamoDB > Summary and Clean Up

Summary and Clean Up

Congratulations! You have made it to the end of the workshop.

In this workshop you explored capturing item level changes on a DynamoDB table using DynamoDB Streams and Kinesis Data Streams. In this instance, you wrote the previous version of updated items to a different DynamoDB table. By applying these same techniques, you can build complex event driven solutions that are triggered by changes to items you have stored on DynamoDB.

If you used an account provided by Workshop Studio, you do not need to do any cleanup. The account terminates when the event is over.

If you used your own account, please remove the following resources:

The Lambda Function Event Source Mappings:

UUID_1=`aws lambda list-event-source-mappings --function-name create-order-history-kds --query 'EventSourceMappings[].UUID' --output text`
UUID_2=`aws lambda list-event-source-mappings --function-name create-order-history-ddbs --query 'EventSourceMappings[].UUID' --output text`
aws lambda delete-event-source-mapping --uuid ${UUID_1}
aws lambda delete-event-source-mapping --uuid ${UUID_2}

The AWS Lambda functions created during the labs:

aws lambda delete-function --function-name create-order-history-ddbs
aws lambda delete-function --function-name create-order-history-kds

The AWS Kinesis data stream created during the labs:

aws kinesis delete-stream --stream-name Orders

The Amazon DynamoDB tables created in the Getting Started section of the lab:

aws dynamodb delete-table --table-name Orders
aws dynamodb delete-table --table-name OrdersHistory

The Amazon SQS queues created during the labs:

aws sqs delete-queue --queue-url https://sqs.${REGION}.amazonaws.com/${ACCOUNT_ID}/orders-ddbs-dlq
aws sqs delete-queue --queue-url https://sqs.${REGION}.amazonaws.com/${ACCOUNT_ID}/orders-kds-dlq

The IAM policies attached to the IAM execution roles you created:

Delete IAM Policies

The AWS IAM execution roles created for the lambda functions:

Delete IAM Roles

This should wrap up the cleanup process.
