Magento 2 : Where is product url key handled(crud) during product edit?

Question

I'm debugging url rewrites in M2.

• One can change the product url key in catalog/product/edit in the Search Engine Optimization tab

• I'm looking at Magento\Catalog\Controller\Adminhtml\Product\Save::execute yet I see nothing related to url keys.

• Q: Who is in charge with of url_rewrites CURD? Where are url_rewrites handled during product update?

Create a Observer for product save after event

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Event/etc/events.xsd">
    <event name="catalog_product_save_after">
        <observer name="test_name" instance="YOUR_NAMESPACE\YOUR_MODULENAME\Observer\Productsaveafter" />
    </event>
</config>

create Productsaveafter.php at below path

app\code\YOUR_NAMESPACE\YOURMODULE\Observer

<?php

namespace YOURNAMESPACE\YOURMODULENAME\Observer;

use Magento\Framework\Event\ObserverInterface;

class Productsaveafter implements ObserverInterface
{    
    public function execute(\Magento\Framework\Event\Observer $observer)
    {
        $_product = $observer->getProduct();  // you will get product object
        $_product->setUrlKey($url);
        $_product->save();    
    }   
}
