Ent Multi Process

This feature is still under development

Sidekiq Enterprise has the ability to start and manage multiple Sidekiq worker processes, like Unicorn or Puma. With multi-process mode, you get two advantages: significant memory savings by sharing memory between processes and running multiple processes on a single Heroku dyno, allowing you to minimize your dyno costs.

The term for running multi-process is swarm. A swarm has a master process and N worker processes.

Starting a Swarm

Sidekiq Enterprise provides a sidekiqswarm binary. This binary is designed to run under Upstart, Systemd or Foreman. It does not allow old-style options like --daemonize, --logfile or --pidfile.

sidekiqswarm [options]

Start and supervise a swarm of Sidekiq processes.
All arguments are passed to each Sidekiq instance.
Do not provide `-i` as sidekiqswarm will automatically generate it.

You may not use the `-d`, `-L` or `-P` options.

Use the COUNT and INDEX environment variables to control sidekiqswarm.

COUNT	Number of Sidekiq processes to start, defaults to number of cores
INDEX	Starting index for Sidekiq Pro's reliable fetch, defaults to 0

Example:
COUNT=5 bundle exec bin/sidekiqswarm -r ./myworker.rb

COUNT defaults to the number of cores on the machine.

Controlling a Swarm

You may send the TERM and USR1 signals to the master process and it will pass those signals to the underlying children.
