};

## Properties

- `applyOn`: string — When set to `PublishedVersions` , Lambda creates a snapshot of the execution environment when you publish a function version.

- `optimizationStatus`: string — When you provide a [qualified Amazon Resource Name (ARN)](https://docs.aws.amazon.com/lambda/latest/dg/configuration-versions.html#versioning-versions-using) , this response element indicates whether SnapStart is activated for the specified function version.
