12 12  Let's imagine we are developing a backend API for an online store and we already have a method {{code language="none"}}ProductService.getInfo{{/code}} for the entity {{code language="none"}}Product{{/code}}. The task on the frontend is to implement the logic of adding products to the cart and updating product information upon request (for example, when opening the cart, we need to update information about the products the user added: availability, prices, descriptions, etc.).

16 16  A task is set for the backend to create a separate API method that returns a collection of objects by an array of identifiers.

This must be done despite having a method that can return one product by its id.

205 205  When receiving an array of requests, the RPC Server creates a queue of [[Symfony Process>>https://symfony.com/doc/current/components/process.html]], i.e., it runs CLI commands that are processed asynchronously. In a while loop, the state of the processes is checked, and if a result is obtained, it is added to the response array. If there is no response before the timeout expires, an error is returned indicating that the request was not processed.
