Cache keys are now used exclusively to delete one or multiple queries, like tags. Multiple queries using the same key will yield different results, as these will not share the same cache key anymore.
If you need to keep the same functionality, use your application Cache directly.
use App\Modesl\User;
$users = cache()->remember('users', 60, function () {
return User::all();
})Idempotent queries have been removed. Cached queries only work for SELECT procedures, like first() or get().
As an alternative, you can use the remember() method of your application cache for the same effect:
cache()->remember('idempotent', 60, function () {
Article::whereKey(10)->increment('unique_views');
return true;
})If for some reason you where using the query hashes, 2.x incorporates the connection name into the hash. This means that the cached query will be usable only for the given connection.
