Redis pool share between Sidekiq & Rails

Question

What is the best practice for sharing a Redis connection pool between Rails and Sidekiq?

I did this in the initializer:

Sidekiq.configure_client do |config| pool = ConnectionPool.new(size: 1, timeout: 5) { Redis.new(host: redis_config['host'], port: redis_config['port'], db: redis_config['database']) } config.redis = pool Redis.current = pool end Sidekiq.configure_server do |config| pool = ConnectionPool.new(size: 10, timeout: 5) { Redis.new(host: redis_config['host'], port: redis_config['port'], db: redis_config['database']) } config.redis = pool Redis.current = pool config.server_middleware do |chain| chain.add Kiqstand::Middleware end end 

But setting up the Rails Redis pool in the Sidekiq block is not very clean ... Any ideas?

After looking at Sidekiq sources, Sidekiq.server? method should be the best option. I changed the initializer code for this:

 # Redis config Redis.current = ConnectionPool.new(size: (Sidekiq.server? ? 15 : 1), timeout: 5) do Redis.new host: redis_config['host'], port: redis_config['port'], db: redis_config['database'] end # Sidekiq config Sidekiq.configure_client do |config| config.redis = Redis.current end Sidekiq.configure_server do |config| config.redis = Redis.current config.server_middleware do |chain| chain.add Kiqstand::Middleware end end
