   - you can pass any `storage` to it that adheres to the `AsyncStorage` or `Storage` interface - the example below uses the async-storage from React Native.
 - Pass that `persister` as an option to your Query. This can be done either by passing it to the `defaultOptions` of the `QueryClient` or to any `useQuery` hook instance.
   - If you pass this `persister` as `defaultOptions`, all queries will be persisted to the provided `storage`. You can additionally narrow this down by passing `filters`. In contrast to the `persistClient` plugin, this will not persist the whole query client as a single item, but each query separately. As a key, the query hash is used.
