PageBuilder "Products" memory exhaustion

[ioweb-gr]

Preconditions and environment

• 2.4.7-p2
• A large catalog with over 4m products of which the majority is configurable products

Steps to reproduce

1. Navigate to Content -> Pages
2. Add a new page
3. Add a new element of type "Products"
4. Try to work with the conditions
5. Watch the system crawl to a halt

firefox_ZwX539ahmb.mp4

Internally the system will invoke function \Magento\PageBuilder\Model\Catalog\ProductTotals::getProductTotals which ends up in memory exhaustion

 PHP Fatal error:  Allowed memory size of 805306368 bytes exhausted (tried to allocate 38080004 bytes) in vendor/magento/zend-db/library/Zend/Db/Adapter/Abstract.php on line 875

I've tried increasing up to 12GB and the error is the same.

Expected result

The counts are calculated properly and the system doesn't crash

Actual result

Memory is exhausted

Additional information

After creating an around plugin on the mentioned function this is how fast it loads

<?php

namespace Ioweb\MagentoPageBuilderBugFix\Plugin;


use Magento\PageBuilder\Model\Catalog\ProductTotals;

class DisableGetProductTotalsDueToSlowness
{
    /**
     * @param ProductTotals $subject
     * @param callable $proceed
     * @param string $conditions
     * @return array
     */
    public function aroundGetProductTotals(ProductTotals $subject, callable $proceed, string $conditions): array
    {
        return [
            'total' => 0,
            'disabled' => 0,
            'notVisible' => 0
        ];
    }
}
