Hi, I have a graph-backed asset defined by
@graph_asset
. It is self-contained in a sense that it loads the necessary data in the first op and materializes the results in the last, but it still have some logical dependencies on other assets. I wanted to map these in the manner of
non_argument_deps
for “normal”
@asset
‘s but couldn’t find a nice way. I ended up “swallowing” the graphs inputs in the first op using
In(Nothing)
for each input, but it feels dirty, especially because it will invoke
load_input
on the upstream assets’ io managers for nothing. Am I missing something here?
