Is there a way to stop a job from executing?

Question

I am using delayed_job to perform as simple task: Open a cvs file(it contains a list of emails) and print every line to a debug log.

Since the file is big, that should take some time.

I enqueue the job with CSVJob.perform_later("test")

This is the active_job:

class CVSJob < ApplicationJob

  queue_as :default

  def perform(job_name)

    job_logger = Logger.new("#{Rails.root}/log/delayed_job.log")

    [..code omitted...]
    CSV.foreach(file_path, headers: true, col_sep: ",") do |row|
        sleep 0.05
        job_logger.debug "------------------------------->"
        job_logger.debug row.inspect
      end
    end

  end

Now, if I login into the rails console and type:

>Delayed::Job.all 

I can see the job running.

But when I delete the job with Delayed::Job.delete_all and no job appears in the delayed_jobs table, the job is still running.

Or, I can find the job id of the job and i can do a simple job.destroy! and the job is deleted from the table.

But(!!) the job is still running! because I see the debug log still executing by doing a simple

    tail -f delayed_job.log
    

Job stops performing when it goes through the whole csv file.

The only way to really "kill" the job is to restart the delayed_job worker. But this defeats the whole purpose of controlling the execution of the job in every aspect.

Is there something that I am doing wrong?

Thank you in advance
