type PassthroughClient 

type PassthroughClient struct {
	// contains filtered or unexported fields
}

func NewPassthroughClient 

func NewPassthroughClient(configPath string) (*PassthroughClient, error)

NewPassthroughClient returns a client that satisfies the persistent_store.Client interface, which is used by the orchestrator during bootstrapping. The passthrough store uses the storage as the source of truth, so it doesn't actually store anything. Instead, the store is pre-populated with backend objects from one or more backend config files prior to bootstrapping. The volume info is then read directly from the storage controllers during the bootstrapping process. The passthrough store does not need to persist any objects, including transactions and storage classes, once the orchestrator has started. The passthrough store is primarily useful for the Docker Volume Plugin use case, which doesn't easily support a separate persistence layer and has no support for storage classes.

func (*PassthroughClient) GetBackends 

func (c *PassthroughClient) GetBackends(context.Context) ([]*storage.BackendPersistent, error)

GetBackends is called by the orchestrator during bootstrapping, so the passthrough store returns the persistent backend objects it read from config files.

func (*PassthroughClient) GetVolume 

func (c *PassthroughClient) GetVolume(_ context.Context, volName string) (*storage.VolumeExternal, error)

GetVolume is not called by the orchestrator, which caches all volumes in memory after bootstrapping. So this method need not do anything.

GetVolumes gets up-to-date volume info from each storage backend. To increase efficiency, it contacts each backend in a separate goroutine. Because multiple backends may be managed by the orchestrator, the passthrough layer should remain as responsive as possible even if a backend is unavailable or returns an error during volume discovery.
