Example:

import aws_cdk.triggers as triggers


func = lambda_.Function(self, "MyFunction",
    handler="index.handler",
    runtime=lambda_.Runtime.NODEJS_18_X,
    code=lambda_.Code.from_inline("foo")
)

triggers.Trigger(self, "MyTrigger",
    handler=func,
    timeout=Duration.minutes(10),
    invocation_type=triggers.InvocationType.EVENT
)

Attributes

DRY_RUN: Validate parameter values and verify that the user or role has permission to invoke the function.

EVENT

Invoke the function asynchronously.

Send events that fail multiple times to the function’s dead-letter queue (if one is configured). The API response only includes a status code.

REQUEST_RESPONSE

Invoke the function synchronously.

Keep the connection open until the function returns a response or times out. The API response includes the function response and additional data.
