sidekiq

I'm playing with Rails 4.2 app which uses ActiveJob backed by resque/sidekiq for email scheduling. When a user creates newsletter campaign a new job is created and scheduled on certain date. That's all great but what happens when the user changes the delivery date. In this case every job could check if it should be delivered or not thus invalid jobs would be ignored and only the last one would be executed. This could work but if a user would make 1k edits that would push 1k-1 invalid jobs into queue - not good. I believe that the existing job should be updated or replaced with a new one. As

I have a background job that does a map/reduce job on MongoDB. When the user sends in more data to the document, it kicks of the background job that runs on the document. If the user sends in multiple requests, it will kick off multiple background jobs for the same document, but only one really needs to run. Is there a way I can prevent multiple duplicate instances? I was thinking of creating a queue for each document and making sure it is empty before I submit a new job. Or perhaps I can set a job id somehow that is the same as my document id, and check that none exists before submitting it?

I think I am missing something since I couldn't find in the docs how to write the username and password for the redis instance to use with sidekiq.. Is there a way to do this? Or is it through ENV vars? Sidekiq passes unrecognized redis options directly to the Redis driver: config.redis = { password: 'bar' } And redis does not have the concept of users so there's only password. 来源： https://stackoverflow.com/questions/25970513/configure-redis-auth-on-sidekiq

I want to schedule and run a lot of jobs in the background during a web application execution. The web app is built on top of Symfony 2 and Doctrine 2. I know the job-processing can be done with libraries like Resque or Sidekiq. However, these libraries and my application are written in different languages, so I am wondering how I can run Sidekiq jobs written in Ruby which should integrate with my app written in PHP. What I'm asking myself is if the only way to do this is rewriting a large amount of code to query the database from PHP to ruby, to be able to execute the job in Sidekiq/Resque.

Sidekiq documentation suggests I can only control the global concurrency of sidekiq, rather than per queue. I am raising a question here with hope that there's a solution for a per-queue concurrency setting. Some 3rd party services just won't accept high concurrency, and limiting the entire sidekiq just for those is painful. I'm on sidekiq 3.3 Using Heroku I was able to control concurrency per queue by setting an environment variable in Procfile and then utilizing it in an sidekiq.rb initializer: Sidekiq.configure_server do |config| config.options[:concurrency] = (ENV['SIDEKIQ_WORKERS_PROCFILE
