AWS Lambda function created in PHP that once triggered, moves a message from SQS into DynamoDB.

Prerequisites

Setup Instructions

Clone this repo from GitHub, and navigate into the newly created directory to proceed.

Use Composer to install dependencies

This example requires the use of Composer to install dependencies and set up the autoloader.

Assuming a Composer global installation. https://getcomposer.org/doc/00-intro.md#globally

composer install

AWS Setup

You will need to create AWS credentials as indicated by Serverless.

Also, create a new SQS queue using the default settings. Make note of the ARN for later use.

Lastly, create a new DynamoDB table using the default settings. Make note of the table name and ARN for later use.

Note: Ensure the primary key field name you set for the DynamoDB table matches the message ID in your SQS queue items. For this example we used messageId.

Update Environment

Rename the provided config.yml.dist file to config.yml and update the values as needed from AWS and DynamoDB, then save.

AWS_REGION: us-east-1
AWS_VERSION: latest
AWS_DYNAMODB_TABLE_NAME:
AWS_SQS_ARN:
AWS_DYNAMODB_TABLE_ARN:

Deploy to Lambda

With all the above updated successfully, you can now use Serverless to deploy the app to AWS Lambda.

serverless deploy

Invoke

If there are already messages in SQS, you can test the migration of these from SQS to DynamoDB by invoking the function by using Serverless locally:

serverless invoke -f sqstodynamo

Note: Above shows the use of function name sqstodynamo as specified in the default serverless.yml in this example.

For testing, you can add messages to SQS through the AWS Console website, or you can look at this repo for an example of how to add SQS messages through a typical HTTP POST request containing JSON.

Automate

To automate the usage of this function, you can add the newly created Lambda as a Lambda Trigger for your SQS instance.

By adding the trigger, it ensures that any new SQS messages call the Lambda function to automatically move the message to DynamoDB, therefore, removing the message from SQS.
