Question1: A message queue currently has queue/consumer-wait-for-messages set to true, which allows the consumer process to run until a message is inserted into the queue. A piece of functionality is driven by data stored in the model
\Magento\variable\Model\variable and this value is only loaded once during the consumer run. If the variable is updated we want the consumer to restart so that the new value is loaded into memory without having to reload the variable on each message consumed.
The Adobe Commerce developer has created an after plugin on the \Magento\Variable\Model\variable:: save() function.
How would the developer use the plugin to trigger the consumer restart?

Question2: An Adobe Commerce developer wants to generate a list of products using ProductRepositorylnterf ace and search for products using a supplier_id filter for data that is stored in a standalone table (i.e., not in an EAV attribute).

C) Prevent it from being exported by adding it to the $_disat>iedAttrs class property array:
