Slide 37

Slide 37 text

Why write XML? - fetching data from Magento and dumping it into xml file is quick - xml can be imported by Drupal’s feed importer

Slide 38

Slide 38 text

Why it didn’t work? - Feed importer was damn slow - 10k products imported in 4.5h - Scheduling import with Elysia Cron module was flaky - Scheduled feed importer would add products all over again - resources hungry!

Slide 39

Slide 39 text

Direct save to the db class DatabaseProductPersister implements ProductPersister { private $repository; /** * @param ProductRepository $repository */ public function __construct(ProductRepository $repository) { $this->repository = $repository; } public function saveAll(ProductList $productList) { foreach ($productList as $product) { $this->repository->save($product); } } }

Slide 40

Slide 40 text

Why direct save to the db? - Drupal promises data structure won’t ever change - It’s fast - 40k products in 2 minutes - It works!
