Write S3 Event Message Into DynamoDB Using Lambda Function

Write S3 Event Message Into DynamoDB Using Lambda Function

Learn to write a lambda function to put S3 event message into DynamoDB table with S3 object creation as the trigger using SAM in Cloud9.


The objective of this article is to create a lambda function that will parse the event time and object key from an S3 event message when a new object is created/uploaded into the S3 bucket. The lambda function will also put these datas into the DynamoDB table.

Now, let’s discuss about the services and tools that we’ll use in this project.

AWS Lambda

AWS lambda lets the user to run code without provisioning or managing servers and the user needs to pay for how much they use. The user can also scale it up and down according to their needs.


Amazon S3 has a simple web services interface that you can use to store and retrieve any amount of data, at any time, from anywhere on the web.

Serverless Application with API Gateway, AWS Lambda and DynamoDB using SAM.

The objective of this article is to create two lambda functions. Out of which, one function will write datas to the DynamoDB table and the other function will read datas from the DynamoDB table. Moreover, both the functions will be invoked by API Gateway calls. In this tutorial, you'll Learn to build a serverless application in your local system and deploy into AWS Cloud using SAM.

Upload to AWS S3 using a Node.js Script or AWS Lambda

I’ve been working through the AWS SDK for S3 trying to make sense of it. It’s definitely not straight forward and lacking some decent complete examples. Anyway, I’ve figured out how to upload an object to S3 using Lambda and also using a Node.js script and thought I would share it with all of you. Now that I can upload objects with Lambda as per my other article React.js API calls to AWS Lambda, API Gateway and dealing with CORS this also means I’m able to initiate this from React.js via API Gateway. In this tutorial, you'll see Upload to AWS S3 Using a Node.js Script or AWS Lambda

Deploy AWS Lambda and DynamoDB using Terraform

The objective of this article is to deploy an AWS Lambda function and a DynamoDB table using Terraform, so that the Lambda function can perform read and write operations on the DynamoDB table. Here, we won’t use any other AWS services to trigger the Lambda function. Instead, we’ll trigger the Lambda function using the test events that is already present in the Lambda console. In this tutorial, you'll see how to Deploy AWS Lambda and DynamoDB using Terraform
