Is the idea here the following? You want to use inversion-of-control such that I provide a function
f
to a component that takes the above dict an an input. Then I can do whatever I like inside the function
f
and return a different dict as output. If the output dict of
f
changes, the component is rerun; otherwise, the old output of the component is used?
Yes exactly ! this way you can say "the code stayed the same, i.e. either ignore it when you compare/hash previous steps, or have a string that represent that change that is invariant to the factoring (not sure how one would do that, If i remember correctly this is NP-complete 😛 ) Anyhow just to explain how it works the new returned dict is then hashed, and that hash is used to look for previous runs, hence cached execution. Make sense ?
