2.4.5 EE Graphql Product Collection flat table disabled

[alexmtch]

Preconditions and environment

• Magento version : 2.4.5 EE
• Anything else that would help a developer reproduce the bug

Steps to reproduce

Go on vendor/magento/module-catalog/Model/ResourceModel/Product/Collection.php in the addAttributeToSelect method.

On my project $this->isEnabledFlat() is always to false causing on some graphql request (add to cart) large execution times dues to vendor/magento/module-quote/Model/ResourceModel/Quote/Item/Collection.php method _assignProducts loading all quote_item attributes.

I found out that in the vendor/magento/module-catalog/Model/ResourceModel/Product/Collection.php constructor, \Magento\Catalog\Model\Indexer\Product\Flat\State $catalogProductFlatState is passed.

And the $catalogProductFlatState->isAvailable() method is alway false dues to the $isAvailable instruction in the constructor false by default.

I found out that in vendor/magento/module-catalog/etc/frontend/di.xml it's set to true :

<type name="Magento\Catalog\Model\Indexer\AbstractFlatState">
    <arguments>
        <argument name="isAvailable" xsi:type="boolean">true</argument>
    </arguments>
</type>
<type name="Magento\Catalog\Model\Indexer\Product\Flat\State">
    <arguments>
        <argument name="isAvailable" xsi:type="boolean">true</argument>
    </arguments>
</type>

Or this is not set in any [...]/etc/graphql/di.xml

Fixing this on the module-catalog-graphql fix both issues. I dot found the correlation between $catalogProductFlatState and $_flatEnabled but it fix the issue. Maybe someone could give me more explanations...

Steps

1. Enable Use Flat Catalog Category and Use Flat Catalog Product from admin panel on path Stores -> Settings -> Configuration -> Catalog -> Catalog -> Storefront

2. Clear the cache.
3. Try to add the product to the cart from the frontend, it will return true for isAvailable:

4. But in GraphQL it is returning false:

Expected result

Flat should be enabled for collections on graphql scope

Actual result

Flat is not enabled for collections on graphql scope
