How to clear all the jobs from Sidekiq?

I am using sidekiq for background tasks in Rails application. Now the numbers of jobs becomes more, so I want to clear all the jobs. I tried the following command in console

Sidekiq::Queue.new.clear

but it was giving following error.

NameError: uninitialized constant Sidekiq::Queue 

How do I clear all the jobs from sidekiq?

You can do as it says on the issue 1077 or as reported in this blog at noobsippets

Both suggest we do the following, and can be done on rails console:

Sidekiq.redis(&:flushdb)

Caution: This command will clear all redis records. I suggest not using it in production

another approach would be

redis-cli --scan --pattern users: * | xargs redis-cli del

according to this blog

Clear Sidekiq Jobs commands:

require 'sidekiq/api'

# Clear retry set

Sidekiq::RetrySet.new.clear

# Clear scheduled jobs 

Sidekiq::ScheduledSet.new.clear

# Clear 'Dead' jobs statistics

Sidekiq::DeadSet.new.clear

# Clear 'Processed' and 'Failed' jobs statistics

Sidekiq::Stats.new.reset

# Clear all queues

Sidekiq::Queue.all.map(&:clear)

# Clear specific queue

stats = Sidekiq::Stats.new
stats.queues
# => {"main_queue"=>25, "my_custom_queue"=>1}

queue = Sidekiq::Queue.new('my_custom_queue')
queue.count
queue.clear

According to this issue on Github: https://github.com/mperham/sidekiq/issues/1732 you now need to

require 'sidekiq/api'

As of latest Sidekiq, just blow it up:

require 'sidekiq/api'

q = Sidekiq::Queue.new
q.💣

Yes, the command to clear all is literally a bomb emoji. Also works for Sidekiq::RetrySet.

Or if you're no fun you can use q.clear

redis-cli flushdb

You can also use redis-cli flushall

Use Rails runner in one line

rails runner 'Sidekiq.redis { |conn| conn.flushdb }'

You can use this for clearing all the jobs

require 'sidekiq/api'

Sidekiq::Queue.all.each(&:clear)

require 'sidekiq/api'

Sidekiq::Queue.all.each {|x| x.clear}

All Sidekiq tasks are saved in "Redis".

You can clean "Redis" by this command

redis-cli flushall

If you want to delete jobs from specific queues try:

queue = Sidekiq::Queue.new("default")
queue.each do |job|
  job.klass # => 'TestWorker'
  job.args # => ['easy']
  job.delete if job.jid == 'abcdef1234567890' || job.klass == 'TestWorker'
end

I realized that Sidekiq.redis { |conn| conn.flushdb } removes all keys from the redis database. There is a safer way to clear all sidekiq queues using redis-cli:

redis-cli keys "*queue:*" | xargs redis-cli del

The same can be achieved with Sidekiq API (see Ravi Prakash Singh answer)
