Adobe Commerce AD0-E716 Adobe Study Notes

To allow theis_delayedEAV attribute to be used in the .phtml cart page, the developer needs to create a new file calledetc/catalog_attributes.xmi. This file will contain the definition of theis_delayedattribute.

The following code shows how to create theetc/catalog_attributes.xmifile:

XML

Is Delayed

This attribute indicates whether the product is delayed.

10

false

Once theetc/catalog_attributes.xmifile has been created, theis_delayedattribute will be available in the .phtml cart page. The attribute can be accessed using thegetIsDelayed()method of theProductclass.

PHP

$product = $block->getProduct();

$isDelayed = $product->getIsDelayed();

TheisDelayedvariable will contain the value of theis_delayedattribute. If the value of the attribute is 1, then the product is delayed. If the value of the attribute is 0, then the product is not delayed.

The developer can use the plugin to trigger the consumer restart by calling the function \Magento\Framework\MessageQueue\Consumers\TriggerRe5tartInterface:trigger(). This function will write a flag to the cache storage that will be checked by the consumer process. If the flag is set, the consumer process will terminate itself and restart with the updated configuration.

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.

Two features that come out of the box with Adobe Commerce Cloud are Support ACL and Fastly. Support ACL is a feature that allows the developer to manage access control lists for different users and roles on the Adobe Commerce Cloud platform. The developer can create and assign permissions for different actions and resources on the project and environment levels. Fastly is a cloud-based caching service that improves site performance and security forAdobe Commerce Cloud projects. Fastly provides features such as CDN, image optimization, WAF, DDoS protection, etc. Verified References: [Magento 2.4 DevDocs] 3
