is turning off deepequal check still supported?

[stefanprobst]

according to docs, setting config.isDataEqual = () => false will disable the default deepequal check for query results.

however, it looks like in the current version, query results will always be deep compared before isDataEqual is run:
https://github.com/tannerlinsley/react-query/blob/master/src/core/query.ts#L292-L298

is there a way to avoid this?

Hi! The code you are referring to is to structurally share data between query results, which will indeed traverse through the results. We could create a flag to toggle this behaviour, but may I ask why you want to avoid it?

i'm working with an unnecessarily large payload from an api i have no control over. so far, i have preferred to just re-render, rather than traversing that.

switching the deepequal default off is explicitly mentioned early in the docs, so it would be great if this was still possible (at least until v3)

thanks for your work on react-query!

There is now a structuralSharing query option which you can use to turn it off :)

awesome, thanks!
