LambdaInvocationType¶

class aws_cdk.aws_stepfunctions_tasks.LambdaInvocationType(value)¶

Bases: enum.Enum

Invocation type of a Lambda.

ExampleMetadata: infused

Example:

# fn: lambda.Function


submit_job = tasks.LambdaInvoke(self, "Invoke Handler",
    lambda_function=fn,
    payload=sfn.TaskInput.from_json_path_at("$.input"),
    invocation_type=tasks.LambdaInvocationType.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 it’s 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.
