# FOR BUSY JOBS
# take the process_id from the /busy page in sidekiq and kill the longest running one.
workers = Sidekiq::Workers.new
long_process_id = 'integration.3:4:71111aaa111' # Eg: 'integration.3:4:71d1d7f4ef5a'
workers.each do |process_id, thread_id, work|
  process = Sidekiq::Process.new('identity' => process_id)
  process.stop! if process_id == long_process_id
end

# FOR SCHEDULED JOBS
# you need to know the jid to make this happen
jid = 'scheduled111aaa222' # Eg: 'e460064eda529b97e93314d4'
job = Sidekiq::ScheduledSet.new.find_job(jid)
job.delete # will just remove the job

# FOR RETRY JOBS
# you need to know the jid to make this happen
