这就是我在 NoteWorker 中使用 rake 任务启动的内容。
NoteWorker.rb
class NoteWorker
include Sidekiq::Worker
sidekiq_options queue: "note"
sidekiq_options :failures => true
def perform(model_id)
#do something
end
end
note.rake
namespace :notes do
task :send_note => :environment do
NoteWorker.perform_async(model.id)
end
end
一切按原样工作。但我正在尝试自动缩放，这似乎无法自动缩放多个工作人员，所以我试图将所有队列更改为“默认”而不是自定义名称。但是当我删除sidekiq_options queue: "note"或更改它时，sidekiq_options queue: "default"它会给我这个错误：
"Scaling worker to 1"
