Setquerydata

According tosetquerydata, query key was changed to be exact by default. Is there a way setquerydata not match a query key exactly when using setQueryData? Beta Was this translation helpful?

I'm testing out react-query for a project and am confused about the interaction between optimistic updates and select. And have another query, like the following, in another part of the application. It does not get triggered for re-render by setQueryData. I am only able to get the ability for 'select' to reduce re-renders when a refetch is called. Beta Was this translation helpful?

Anyways, sorry if it's not clear from the docs. Looking at the existing code, this would actually require modifying setQueryData , functionalUpdate , and probably others too, but having access to the full queryKey in the updater function would be very beneficial either as the second argument, or as a property of the second argument, so adding more items than queryKey wouldn't constitute a breaking change in the future. This is the source of my confusion, as it does seem to work similar to this, unless you add a select. Sign up for free to join this conversation on GitHub.

Unfortunately, the updater function in setQueriesData doesn't currently have access to the exact query key. But since the updater function has no knowledge of the queryKey , it cannot know this.
