Magento 2 reindex is a helpful way to notify bots of the search engines about your new or updated information on your online store. Also, it helps to ensure that your users will always see the latest updates on your Magento site. Magento has very complex database architecture that includes many database tables to store information like catalog data, prices, users, and stores. So, to have an instant effect in frontend, the admin store need to reindex all this information in special database tables using indexers. Even having a small change in price or URL , the admin requires reindexing of data to get an effect. In this article, we will show you three methods you can use to reindex in Magento
What Is Magento 2 Reindex?
Reindex Magento 2 is the best solution of transforming data on the front end so that visitors can see it if there is any modification or changes on the Magento 2 store. As you know that, Magento 2 owns a lot of merchant data, which should be accessed, searched and used – catalogs, prices, stores ..etc. They are scattered across different tables. so, to enhance performance, Magento 2 offers they all together in special tables called indexers
Indexers also includes data, which usually are calculated from other properties – for instance, prices. It enables Magento 2 to render catalog pages very fast, without requiring for recalculating prices on-the-fly. However, if you adjust price directly in product, changes will not be showcased because indexer will still includes old recalculated data. To make changes apply, you need to reindex
When Is Magento 2 Reindex Required?
In Magento 2, there are some indexers required, when any changes are made.
- Category products;
- Product categories;
- Product price;
- Product entity attribute value;
- Stock;
- Catalog rule product;
- Catalog product rule;
- Catalog search.
An example of reindexing in Magento 2 is, when changing a product price, the data should be reindexed to be correctly showcased on the frontend. So, “reindex the indexation” would adequately cut down time spent on calculating a final order price containing cart price rules, bundle pricing, discounts, tier pricing, etc.

Instead of manually indexing, you also run a small piece of code in an extension helps you to perform reindexing programmatically in Magento 2.

namespace Vendor\Extension\Controller;
class Myactions extends \Magento\Framework\App\Action\Action
{
protected $indexFactory;
protected $indexCollection;
public function __construct(
\Magento\Indexer\Model\IndexerFactory $indexFactory,
\Magento\Indexer\Model\Indexer\CollectionFactory $indexCollection
){
$this->indexFactory = $indexFactory;
$this->indexCollection = $indexCollection;
}
public function Mycustomaction()
{
$indexerCollection = $this->indexCollection->create();
$indexids = $indexerCollection->getAllIds();
foreach ($indexids as $indexid)
{
$indexidarray = $this->indexFactory->create()->load($indexid);
//If you want reindex all use this code.
$indexidarray->reindexAll($indexid);
//If you want to reindex one by one, use this code
$indexidarray->reindexRow($indexid);

}
