 the same key could be invalidate with one function call::

    use Symfony\Contracts\Cache\ItemInterface;
    use Symfony\Contracts\Cache\TagAwareCacheInterface;

    $value0 = $pool->get('item_0', function (ItemInterface $item) {
        $item->tag(['foo', 'bar'])
    // using autowiring
    public function listProducts(TagAwareCacheInterface $pool)
    {
        $value0 = $pool->get('item_0', function (ItemInterface $item) {
            $item->tag(['foo', 'bar']);

        return 'debug';
    });
 return 'debug';
 });

    $value1 = $pool->get('item_1', function (ItemInterface $item) {
        $item->tag('foo')
 $value1 = $pool->get('item_1', function (ItemInterface $item) {
 $item->tag('foo');

        return 'debug';
    });
 return 'debug';
 });

    // Remove all cache keys tagged with "bar"
    $pool->invalidateTags(['bar']);
        // Remove all cache keys tagged with "bar"
        $pool->invalidateTags(['bar']);
    }

 The cache adapter needs to implement :class:`Symfony\\Contracts\\Cache\\TagAwareCacheInterface``
 to enable this feature. This could be added by using the following configuration.
