LambdaInvokeOperation

Contains the configuration parameters for a Lambda Invoke operation.

Contents

FunctionArn

The Amazon Resource Name (ARN) for the AWS Lambda function that the specified job will invoke on every object in the manifest.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 1024.

Pattern: (arn:(aws[a-zA-Z-]*)?:lambda:)?([a-z]{2}((-gov)|(-iso([a-z]?)))?-[a-z]+-\d{1}:)?(\d{12}:)?(function:)?([a-zA-Z0-9-_]+)(:(\$LATEST|[a-zA-Z0-9-_]+))?

Required: No

InvocationSchemaVersion

Specifies the schema version for the payload that Batch Operations sends when invoking an AWS Lambda function. Version 1.0 is the default. Version 2.0 is required when you use Batch Operations to invoke AWS Lambda functions that act on directory buckets, or if you need to specify UserArguments. For more information, see Automate object processing in Amazon S3 directory buckets with S3 Batch Operations and AWS Lambda in the AWS Storage Blog.

Important

Ensure that your AWS Lambda function code expects InvocationSchemaVersion 2.0 and uses bucket name rather than bucket ARN. If the InvocationSchemaVersion does not match what your AWS Lambda function expects, your function might not work as expected.

Note

Directory buckets - To initiate AWS Lambda function to perform custom actions on objects in directory buckets, you must specify 2.0.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 64.

Required: No

UserArguments

Key-value pairs that are passed in the payload that Batch Operations sends when invoking an AWS Lambda function. You must specify InvocationSchemaVersion 2.0 for LambdaInvoke operations that include UserArguments. For more information, see Automate object processing in Amazon S3 directory buckets with S3 Batch Operations and AWS Lambda in the AWS Storage Blog.
