I want when user clicks on Export to Excel link background/new thread process runs and an email is sent to the user with a link to download a file. I want to know which is best way to achieve this Creating new thread or Background process?

There are three types of messages queues,

  1. No queues - a new thread / process will be triggered for background task, eg: spawn
  2. Database driven - corresponding task will be stored in a table in the database and will be deleted automatically on completion, eg: backgroundrb, delayed job
  3. Message queues - Stored jobs in memory, eg: starling

I haven't used resque, but heard that it is bit complicated to configure. Apart from running tasks in background, if you want to run some repetitive task on regular intervals, you can go for backgroundrb. Otherwise delayed job will be right choice.

You may want to use https://github.com/defunkt/resque or https://github.com/collectiveidea/delayed_job.

You can also watch:
