Grouped product indexer | cache clear fix

[adarshkhatri]

Preconditions (*)

1. magento/module-inventory-cache
2. Magento 2.4.7-p2

What is happening?

MSI has this function in place as around method. Which gets the product IDs from inventory_stock_ID table before and after.
Pay attention to around method here.

inventory/InventoryCache/Plugin/InventoryIndexer/Indexer/Stock/Strategy/Sync/CacheFlush.php

Line 51 in 790c7ff

public function aroundExecuteList(Sync $subject, callable $proceed, array $stockIds)

Then, it also has this function as after method to index grouped products, which happens after the above function (around) runs, meaning at this time, the system has already sent all the grouped product IDs to clear the cache.

inventory/InventoryGroupedProductIndexer/Plugin/InventoryIndexer/Indexer/Stock/Strategy/Sync/ReindexFullPlugin.php

Line 43 in 790c7ff

public function afterExecuteFull(

What this means?

If I have 200 grouped products in my system, every time a single product's (not related to grouped whatsoever) sources deleted/added, then it will send the cache clear request for this product PLUS that 200 grouped products.

Steps to reproduce (*)

1. Make sure you have some grouped products
2. Run bin/magento indexer:reindex inventory

Expected result (*)

1. System should only send impacted products to clear the cache

Actual result (*)

1. System should never send unrelated product to clear the cache
