How can I store a graph asset?

[marcilj]

I'm trying out the graph_asset feature and I don't understand how I'm suppose to store the graph_asset.

Normally I would create and asset and add my IO_Manager so the storage would get handled by default, but graph_asset decorator doesn't have a io_manager_key parameter so I'm confused on how I should handle this.

I could store it directly into a table using and op, but then how could the potential downstream asset of this graph_asset would know how to load the data from this `graph_asset?

I was under the impression that I should/could do something like this but I can't

@op
def my_op():
    return 1

@op
def my_second_op(something):
    return something + 1

@graph_asset(io_manager_key="my_io_manager")
def my_graph_asset(): 
    return my_second_op(my_op())

Found it, the Graph asset is store with the io_manager configured in the last Op of the Graph.

@marcilj can you please explain how you did this? I can't seem to be able to define an io manager on an op.
