Hey guys,

We want to suggest here a new discussion which can maybe turn into a new feature to improve the system.

During the development of some activities involving assincronous tasks, we were thinking about a new way to manage a tasks queue and a new way to get informed about the tasks in the system.

We divided the idea into two parts:

1-) First of all, an idea to the backend take care of a tasks queue, allowing the user to trigger tasks as many as he wants. Any request involving an async task triggered by the user, will be pushed into a queue in the back-end. There will be a consumer of this queue, getting the first task to process, and the others will be set with a "Waiting" status. This "consumer" will manage the queue of tasks. One idea to implement this is using the "Publish Subscribe" Desing Pattern. Another idea is to keep the task with a "Waiting" status in the database, and the consumer consumes from this database instead of a queue (updating the status and message of the task).  
At the moment, we don't have a way to control this queue, when it's necessary, the frontend try to do it. The problem is when the user wants to trigger more then one task, then he can't make a logout in the system because he will lose this queue.

2-) Develop a new tab in Wok to show the tasks in the system. We can show the tasks for each plugin separeted. For example: if the user has kimchi, ginger and gingerbase installed, this tab will contain three sections, each one with a table of tasks containg the id, status (running, waiting, failure, etc), message and target uri of each task. We can develop a filter for this tables too, allowing the user to search the tasks respecting some filters.

The main idea with this suggestion, is a way to display what is happening in the system with the async tasks and allow the user to make more then one async request without waiting for the last getting finished.

All of this is just a suggestion, we are open to any doubts or to discuss and improve this idea. Feel free to any suggestions or criticizes. :)

Thank you.
