Sidekiq 作业已排队但未在 Heroku 上处理

Question

Rails 5.2 redis 4.0.1 sidekiq 5.1.3

Heroku 上的 RedisToGo

过程文件：

web: bundle exec puma -C config/puma.rb
worker: bundle exec sidekiq -e production -C config/sidekiq.yml

sidekiq.yml

development:
  :concurrency: 5
production:
  :concurrency: 6
:queues:
  - default

config/initialize/sidekiq.rb

if Rails.env.production?

  Sidekiq.configure_client do |config|
    config.redis = { url: ENV['REDISTOGO_URL'] || ENV['REDIS_URL'], size: 1 }
  end

  Sidekiq.configure_server do |config|
    pool_size = ENV['SIDEKIQ_DB_POOL'] || (Sidekiq.options[:concurrency] + 2)
    config.redis = { url: ENV['REDISTOGO_URL'] || ENV['REDIS_URL'], size: pool_size }

    Rails.application.config.after_initialize do
      Rails.logger.info("DB Connection Pool size for Sidekiq Server before disconnect is: #{ActiveRecord::Base.connection.pool.instance_variable_get('@size')}")
      ActiveRecord::Base.connection_pool.disconnect!

      ActiveSupport.on_load(:active_record) do
        db_config = Rails.application.config.database_configuration[Rails.env]
        db_config['reaping_frequency'] = ENV['DATABASE_REAP_FREQ'] || 10 # seconds
        db_config['pool'] = pool_size
        ActiveRecord::Base.establish_connection(db_config)
        Rails.logger.info("DB Connection Pool size for Sidekiq Server is now: #{ActiveRecord::Base.connection.pool.instance_variable_get('@size')}")
      end
    end
  end
end

我不知道为什么作业卡在队列中。这项工作在我的本地开发中有效。

感谢任何帮助。

更新！根据这里的评论是 heroku ps:

的输出

=== web (Free): bundle exec puma -C config/puma.rb (1)
web.1: up 2018/06/15 18:49:56 +0700 (~ 5s ago)

=== worker (Free): bundle exec sidekiq -q default (1)
worker.1: crashed 2018/06/15 18:49:51 +0700 (~ 10s ago)

似乎有工人因某种原因坠毁了。

Answer 1

将 Heroku Postgres 作为插件安装，然后将环境变量添加到您的项目中，一切都会正常进行。 - https://elements.heroku.com/addons/heroku-postgresql

Answer 2

在与 Heroku 的技术支持人员交谈后，我发现我需要更改编码 db yaml 文件的方式。

我改成如下：

production:
  url: <%= ENV['DATABASE_URL'] %>

这似乎解决了问题。
