Behavior of query.set / cache.set

Hello,

I am trying to preform some optimistic updates with the SolidStard data loading features. I've found the undocumented

.set

.set

function on

query

query

(previously named

cache

cache

) but can't seem to get it to mutate any data. Calling it seems to have no effect on

createAsync

createAsync

stores.

A couple threads have asked about this but have not received answers. Would anyone be able to shed light on the subject?
