Properties

Merge

A serialized JSON string that contains the configuration object to merge to target devices. The core device merges this configuration with the component's existing configuration. If this is the first time a component deploys on a device, the core device merges this configuration with the component's default configuration. This means that the core device keeps it's existing configuration for keys and values that you don't specify in this object. For more information, see Merge configuration updates in the Amazon IoT Greengrass V2 Developer Guide.

Reset
