Domain-Driven Design in PHP

Migrating our Persistence to Redis

During the sprint and after talking to some mates, you realize that using a NoSQL strategy could improve the performance of your feature. Redis is one of your best friends. Go for it and show me your Listing 4:

class IdeaController extends Zend_Controller_Action{    public function rateAction()    {        $ideaId = $this->request->getParam('id');        $rating = $this->request->getParam('rating');        $ideaRepository = new RedisIdeaRepository();        $idea = $ideaRepository->find($ideaId);        if (!$idea) {            throw new Exception('Idea does not exist');        }        $idea->addRating($rating);        $ideaRepository->update($idea);        $this->redirect('/idea/' . $ideaId);    }}interface IdeaRepository{    // ...}class RedisIdeaRepository implements IdeaRepository
