I am trying to unassign a category from a product. This category has a large number of products assigned to it (like 1500+). I used the code

`$CategoryLinkRepository ->deleteByIds($categoryId, $productSku);`

but this function essentially is un-tagging all this single product from category's assigned product list and saving the category. Which in turn is resulting in a lot of big queries (like real big queries which you won't want to see getting fired at your database) being fired at MySQL and getting timed out? A code snippet is as follows:

 public function deleteByIds($categoryId, $sku)
 
 $category = $this->categoryRepository->get($categoryId);
 $product = $this->productRepository->get($sku);
 $productPositions = $category->getProductsPosition();

 $productID = $product->getId();
 if (!isset($productPositions[$productID])) 
 throw new InputException(__('Category does not contain specified product'));
 
 $backupPosition = $productPositions[$productID];
 unset($productPositions[$productID]);

 $category->setPostedProducts($productPositions);
 try 
 $category->save();
 catch (Exception $e) 
 throw new CouldNotSaveException(
 __(
 'Could not save product "%product" with position %position to category %category',
 [
 "product" => $product->getId(),
 "position" => $backupPosition,
 "category" => $category->getId()
 ]
 ),
 $e
 );
 
 return true;

  If I use a query like delete from catalog_category_product where category_id = 4 and product_id = 46;. Should this work safely? I understand that there could be some garbage data left like urls etc.
