The probable cause for the delay in reflecting the changes on the frontend after a full product import is the combination of the number of products, customer groups and websites. This leads to a huge amount of values being stored in the price index which is too large to be processed at a normal speed. The price index calculates the final price of each product for each customer group and website, taking into account various factors such as tax, discounts, catalog price rules, etc. When there are many products, customer groups and websites, the price index becomes very complex and time-consuming to update.

The next steps to reduce the downtime are to check that the SCD is configured under the build phase and to increase the SCD.THREADS to speed up the build process. The SCD stands for static content deployment, which is the process of generating and deploying static files such as CSS, JS, images, etc. By configuring the SCD under the build phase, the static files are generated before the code is deployed to the production environment, which reduces the downtime during deployment. The SCD.THREADS is a variable that determines how many threads are used for parallel processing during the SCD. By increasing the SCD.THREADS, the developer can improve the performance and efficiency of the SCD process.

The reason why there are records remaining in the inventory_reservation table is that only reservations no longer needed are removed by the cron job. The inventory_reservation table tracks the quantity of each product in each order and creates a reservation for each product when an order is placed, shipped, cancelled or refunded. The initial reservation has a negative quantity value and the subsequent reservations have positive values. When the order is complete, the sum of all reservations for the product is zero. The cron job removes only those reservations that have a zero sum from the table, leaving behind any reservations that are still needed for incomplete orders.

According to the Magento Stack Exchange answer, system.xml is a file that defines the configuration fields for the admin area. Each field can have a validate attribute that specifies avalidation rule for the field value. Magento provides some built-in validation rules, such as phoneUS, which validates a US telephone number. Therefore, to ensure that the option contains a valid US telephone number, the developer needs to add phoneUS to the field in system.xml. Verified References:

The shipping method would display $10 and customers would pay $10 for using the new shipping method. This is because the collectRates method sets the price and cost of the shipping method to 10 in the result object. The price is what is shown to the customer on thefrontend and the cost is what is charged to the customer when they place the order. The handling fee is not used in this case because it is set to zero in the config.xml file. Verified References: [Magento 2.4 DevDocs] [Magento Stack Exchange]

The_transformAttrsclass property array of the importer and exporter classes can be used to specify a serializer class for a particular attribute. The serializer class will be used to convert the attribute value from one format to another when the data is exported or imported.

In this case, the developer can specify a serializer class that will convert the JSON data in themedia_galleryattribute to a string. This will prevent the software that the client is using to modify the exported data from changing the JSON data.

The following code shows how to specify a serializer class for themedia_galleryattribute:

PHP

class MySerializer

{

public function serialize($value)

{

return json_encode($value);

}

public function deserialize($value)

{

return json_decode($value);

}

}

$importer->setSerializer('media_gallery', MySerializer::class);

$exporter->setSerializer('media_gallery', MySerializer::class);

Once the serializer class has been specified, the JSON data in themedia_galleryattribute will be converted to a string when the data is exported or imported. This will prevent the software that the client is using to modify the exported data from changing the JSON data.

To display the "file upload" field and process the actual CSV import, the following two requirements must be met:

• The developer must create a new system configuration setting that specifies the path to the CSV file.
• The developer must create a new controller action that handles the file upload and import process.

Thesystem.xmlfile is used to define system configuration settings. The following XML snippet shows how to define a new system configuration setting for the CSV file path:

XML

/path/to/csv/file

TheController\Adminhtml\ShipmentFeescontroller class is used to handle the file upload and import process. The following code shows how to create a new controller action that handles the file upload and import process:

PHP

public function uploadAction()

{

$file = $this->getRequest()->getFile('shipment_fees_csv_file');

if ($file->isUploaded()) {

$importer = new ShipmentFeesImporter();

$importer->import($file);

}

return $this->redirect('adminhtml/system_config/edit/section/shipment_fees');

}

The following XML will allow the new content type to be a child of slider content types:

slider

improved_slide

Use code with caution. 

This XML will tell Magento that theslidercontent type can haveimproved_slidecontent types as children.
