EventInvokeConfig — AWS Cloud Development Kit 1.204.0 documentation

class aws_cdk.aws_lambda.EventInvokeConfig(scope, id, *, function, qualifier=None, max_event_age=None, on_failure=None, on_success=None, retry_attempts=None)

Bases: Resource

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.

ExampleMetadata:

fixture=_generated

Example:

# 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
)

Parameters:

• scope (Construct)

• id (str)

• function (IFunction) – The Lambda function.

• qualifier (Optional[str]) – The qualifier. Default: - latest version

• max_event_age (Optional[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)

• on_failure (Optional[IDestination]) – The destination for failed invocations. Default: - no destination

• on_success (Optional[IDestination]) – The destination for successful invocations. Default: - no destination

• retry_attempts (Union[int, float, None]) – The maximum number of times to retry when the function returns an error. Minimum: 0 Maximum: 2 Default: 2

Methods

apply_removal_policy(policy)

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 (RemovalPolicy.RETAIN).

Parameters:

policy (RemovalPolicy)

Return type:

None

to_string()

Returns a string representation of this construct.

Return type:

str

Attributes

env

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.

node

The construct tree node associated with this construct.

stack

The stack in which this resource is defined.

Static Methods

classmethod is_construct(x)

Return whether the given object is a Construct.

Parameters:

x (Any)

Return type:

bool

classmethod is_resource(construct)

Check whether the given construct is a Resource.

Parameters:

construct (IConstruct)

Return type:

bool
