- class aws_cdk.aws_lambda.EventInvokeConfig(scope, id, *, function, qualifier=None, max_event_age=None, on_failure=None, on_success=None, retry_attempts=None)
Configure options for asynchronous invocation on a version or an alias.
By default, Lambda retries an asynchronous invocation twice if the function returns an error. It retains events in a queue for up to six hours. When an event fails all processing attempts or stays in the asynchronous invocation queue for too long, Lambda discards it.
# The code below shows an example of how to instantiate this type. # The values are placeholders you should change. import aws_cdk.aws_lambda as lambda_ import aws_cdk.core as cdk # destination: lambda.IDestination # function_: lambda.Function event_invoke_config = lambda_.EventInvokeConfig(self, "MyEventInvokeConfig", function=function_, # the properties below are optional max_event_age=cdk.Duration.minutes(30), on_failure=destination, on_success=destination, qualifier="qualifier", retry_attempts=123 )
IFunction) – The Lambda function.
str]) – The qualifier. Default: - latest version
Duration]) – The maximum age of a request that Lambda sends to a function for processing. Minimum: 60 seconds Maximum: 6 hours Default: Duration.hours(6)
IDestination]) – The destination for failed invocations. Default: - no destination
IDestination]) – The destination for successful invocations. Default: - no destination
None]) – The maximum number of times to retry when the function returns an error. Minimum: 0 Maximum: 2 Default: 2
Apply the given removal policy to this resource.
The Removal Policy controls what happens to this resource when it stops being managed by CloudFormation, either because you’ve removed it from the CDK application or because you’ve made a change that requires the resource to be replaced.
The resource can be deleted (
RemovalPolicy.DESTROY), or left in your AWS account for data recovery and cleanup later (
- Return type
Returns a string representation of this construct.
- Return type
The environment this resource belongs to.
For resources that are created and managed by the CDK (generally, those created by creating new class instances like Role, Bucket, etc.), this is always the same as the environment of the stack they belong to; however, for imported resources (those obtained from static methods like fromRoleArn, fromBucketName, etc.), that might be different than the stack they were imported into.
The construct tree node associated with this construct.
The stack in which this resource is defined.
- classmethod is_construct(x)
Return whether the given object is a Construct.
