In the previous article, we explored the core architecture of Apollo . keyvaluecache package. Install Flipper and open it. Configure caching behavior on a per-field basisWhen Apollo Server resolves an operation, it calculates the result's correct cache behavior based on the most restrictive settings among the result's fields. Bypassing the cache Sometimes you shouldn't use the cache for a particular GraphQL operation. You can interact with data that you previously fetched from your server, and with data that's only available locally. Apollo Kotlin provides two built-in normalized caches for storing and reusing the results of GraphQL operations: An in-memory cache (MemoryCache) A SQLite-backed cache (SqlNormalizedCache) You can use one (or both!) of these caches in your app to improve its responsiveness for most operations. KeyvAdapter simply wraps a Keyv instance and implements the KeyValueCache interface which is required by Apollo Server. Apollo Client supports multiple strategies for What you can do instead of making a query for author(id: 5) (which is a field with an argument that your client hasn't seen before), is just select the author with the id 5 from the cache - for example using the useFragment hook.
