.average_scheduled_poll_interval=(interval) ⇒ Object

How frequently Redis should be checked by a random Sidekiq process for scheduled and retriable jobs. Each individual process will take turns by waiting some multiple of this value.

See sidekiq/scheduled.rb for an in-depth explanation of this value
