Thus, we have created Lambda function called newlambdafordynamodb as shown. Add the role and will use it while creating AWS Lambda function. Observe that the policies added are newpolicyfordynamdb, awslambdafullaccess, cloudwatchfullaccess and amazonsesfullaccess. Select Role from left side and enter the details. Add the policy to the role to be created. Enter the name of the policy, description etc as shown below −Ĭlick on create policy to save it. We will get ARN details from customer table created as shown below −Ĭlick Add button to save the changes.
Now, select table and Add ARN to it as shown. When you click it, you can see a screen as follows − For resources, we will select the table resource type actions. For Actions we have taken all Dynamodb actions ie access to list, read and write. Observe that the service we have selected is DynamoDB. Let us create a policy to be used only for the DynamoDB table created earlier − To create role, Go to AWS services and click IAM. We can add items to the table created as follows −Ĭlick Items and click Create item button as shown −Ĭreating Role with Permissions to Work with DynamoDB and AWS Lambda Click on Create button to add the table to dynamodb. We have named the table as customer with primary key for that table as cust_id. Now, click Create table to create the table as shown. Select DynamoDB.ĭynamoDB shows the options as shown below − Go to AWS Services and select DynamoDB as shown below. The basic block diagram that explains the flow of the example is as shown below − Create Table in DynamoDB with Primary Key Triggering AWS Lambda function once the data is entered and sending mail using Amazon SES service. This example will help you to understand the following operations −Ĭreating a table called customer in Dynamodb table and how to enter data in that table. We are going to work out on following example which shows the basic interaction between DynamoDB and AWS Lambda. Let us discuss each of this step in detail. To use Amazon DB and AWS Lambda, we need to follow the steps as shown below −Ĭreate a table in DynamoDB with primary keyĬreate a role which will have permission to work with DynamoDBand AWS Lambda. In this chapter, we will work on a simple example that will add items to the DynamoDB table and AWS Lambda which will read the data and send mail with the data added.
