### Using Schema directive directive `@cacheControl`

For a schema first approach, the `@cacheControl` directive can be used to define the TTL.

Notice that the global default TTL can only be define in the plugin options `ttl` and not via the directive.

```ts filenmae="Response Cache configuration with TTL using @cacheControl directive"
import { cacheControlDirective } from '@graphql-yoga/plugin-response-cache'

const typeDefs = /* GraphQL */ `
# the directive needs to be defined in the schema
${cacheControlDirective}

type Query {
# cache operations selecting Query.lazy for 10 seconds
lazy: Something @cacheControl(maxAge: 10000)
}

# only cache query operations containing User for 500ms
type User @cacheControl(maxAge: 500) {
#...
}
`
```

## Invalidations via Mutation

When executing a mutation operation the cached query results that contain type entities within the Mutation result will be automatically be invalidated.
