Placeholder data allows a query to behave as if it already has data, similar to the initialData option, but the data is not persisted to the cache. This comes in handy for situations where you have enough partial (or fake) data to render the query successfully while the actual data is fetched in the background., Whether you need to poll an API at a regular interval, fetch data in the background, or transform the data before it’s returned to the component, options like refetchInterval, refetchIntervalInBackground, and select make it easy to get the job done..
