With the next inv command we will create a new bucket on S3 called aws_scala_lambda_bucket. you could be processing a large S3 file and it’s more efficient (and cheaper) to cache the content of the S3 file. The Lambda function will always write to the same S3 Key with the same content, so the only t. The handler has the details of the events. Next, therefore, write a function that accepts the file object and retrieves an appropriate signed request for it from the app. The following arguments are supported: policy_id (Optional) - An ID for the policy document.

Create an IAM role (execution role) for the Lambda function that also grants access to the S3 bucket. AWS Lambda functions can be triggered by different events, including events from AWS services such as S3 (such as changes to S3 buckets), DynamoDB (such as updates to a table in the database), CodeCommit, CloudWatch (such as as a response to an alarm), and AWS IoT. While the API Gateway is primarily designed to serve JSON data, you can be configure it to serve plain HTML files and use it as a rudimentary web server.

The best thing about setting the Lambda S3 trigger is, whenever a new file is uploaded, it will trigger our Lambda. With the next inv command we will create a new bucket on S3 called aws_scala_lambda_bucket. buildspec-lambda. For any object uploaded to a bucket, S3 will invoke our Lambda function by passing event information in the form of function parameters. Writing to S3 is much simpler from a Lambda than from a web service sitting outside of AWS. Implementation. Next, create your function in the appropriate file for your desired Lambda runtime.
