What is Apollo Client Cache and how does it work?

Apollo Client Cache is a powerful caching mechanism used in Apollo Client to manage GraphQL data efficiently. It stores query results and allows for quick retrieval, reducing the need for repeated network requests.

How does it improve performance in my application?

By caching data, Apollo Client reduces the number of network requests, leading to faster load times and a smoother user experience. It also allows for optimistic UI updates.

Can I customize the cache behavior?

Yes, you can customize the cache behavior using various policies like 'cache-first', 'network-only', or 'cache-and-network' to suit your application's needs.

What happens if the data in the cache becomes stale?

If the cached data becomes stale, you can use cache invalidation strategies or refetch queries to ensure your application displays the most up-to-date information.
