Connecting Lambda to DynamoDB
Overview
Domain expertise for connecting AWS Lambda functions to DynamoDB tables, including IAM execution role creation, function deployment, DynamoDB stream configuration, and event source mapping setup.
Connect a Lambda function to DynamoDB
To set up end-to-end Lambda-DynamoDB integration with IAM roles, streams, and event source mapping, follow the procedure exactly. See [Lambda-DynamoDB connection procedure](references/lambda-dynamodb-connection.md).
Troubleshooting
Lambda function not triggering
Verify the event source mapping is active, DynamoDB streams are enabled with the correct view type, and the execution role has proper permissions. See the full [procedure](references/lambda-dynamodb-connection.md) for details.
Permission denied errors
Check the IAM role has `AWSLambdaDynamoDBExecutionRole` attached and the trust policy allows Lambda to assume it.
Function timeout issues
Increase the timeout setting or adjust the batch size in the event source mapping.
