AliasOptions

class aws_cdk.aws_lambda.AliasOptions(*, max_event_age=None, on_failure=None, on_success=None, retry_attempts=None, additional_versions=None, description=None, provisioned_concurrent_executions=None)

Bases: aws_cdk.aws_lambda.EventInvokeConfigOptions

Options for lambda.Alias.

Parameters

  • 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

  • additional_versions (Optional[Sequence[VersionWeight]]) – Additional versions with individual weights this alias points to. Individual additional version weights specified here should add up to (less than) one. All remaining weight is routed to the default version. For example, the config is Example:: version: “1” additionalVersions: [{ version: “2”, weight: 0.05 }] Then 5% of traffic will be routed to function version 2, while the remaining 95% of traffic will be routed to function version 1. Default: No additional versions

  • description (Optional[str]) – Description for the alias. Default: No description

  • provisioned_concurrent_executions (Union[int, float, None]) – Specifies a provisioned concurrency configuration for a function’s alias. Default: No provisioned concurrency

Attributes

additional_versions

Additional versions with individual weights this alias points to.

For example, the config is Example:

version: "1"
additionalVersions: [{ version: "2", weight: 0.05 }]

Then 5% of traffic will be routed to function version 2, while the remaining 95% of traffic will be routed to function version 1.
