Field-level subscriptions / selector support (similar to Zustand)

[jayseo5953]

Hi! Really enjoying Reactive Data Client so far — especially the normalized cache and endpoint model.

I had a question about subscription granularity.

From what I understand, subscriptions are at the entity/query level, so if one field on an entity changes, all components consuming that entity rerender — even if they only use unrelated fields.

Is there any support (or plans) for field-level subscriptions or selectors, similar to Zustand?

For example:

const title = useSuspense(getTodo, { id }, data => data.title);

so that components only rerender when the selected value changes.

Or is the current recommendation to:

• split components
• pass smaller props
• rely on React.memo

Just trying to understand the intended pattern for:

• large forms
• complex pages
• data tables

Thanks!

React compiler should handle this. But tell me if you find a case where it doesn't!
