Properties

Property	Alerts	Modifiers	Type	Description
cacheSnapshot	Alpha	optional	boolean	Tell driver to cache the fetched snapshot. Driver is supposed to cache the fetched snapshot if this is set to true. If undefined, then it is upto the driver, to cache it or not.
fetchSource	Alpha	optional	FetchSource	Specify if you want default behavior of the driver to fetch the snapshot like lets say simultaneously fetch from network and cache or specify FetchSource.noCache to just fetch from network.
loadingGroupIds	Alpha	optional	string[]	List of loading groupId of datastores for which the snapshot needs to be fetched. If not provided, content with default/missing groupIDs will be requested from the service. It is upto the service, to include snapshot for content with groupIds or not. Don't provide anything here for fetching content for initial container boot.
scenarioName	Alpha	optional	string	Indicates scenario in which the snapshot is fetched. It is a free form string mostly used for telemetry purposes.
versionId	Alpha	optional	string	Version of the snapshot to be fetched. Certain storage services just keep 1 snapshot for the container, so specifying version is not necessary for storage services.
