             print_mode: Accepts the same values as `stream_mode`, but only prints the output to the console, for debugging purposes. Does not affect the output of the graph in any way.
-            output_keys: The output keys to include in the result.

             durability: The durability mode for the graph execution, defaults to `"async"`.
                 Options are:
 
                 - `"sync"`: Changes are persisted synchronously before the next step starts.

-            The result of the computation. If `stream_mode` is `"values"`, it returns the latest value.
-            If `stream_mode` is `"chunks"`, it returns a list of chunks.
