问题
In my current project I am doing some process in background by using Delayed Job gem. It's working fine in local but in production jobs are inserted into Delayed Job table but DJ not picking few jobs from that DJ table. Could any one have idea how Delayed Job will pick up jobs from Delayed Job table.
Below is the Delayed job code in my project:
Delayed::Job.enqueue(ProposalJob.new(current_user, @proposal, request.host, params[:proposal][:revision_notes], params[:proposal][:close_date]), :queue => 'publishing')
Delayed job configuration in my project:
Delayed::Worker.destroy_failed_jobs = false
Delayed::Worker.max_attempts = 3
Delayed::Worker.max_run_time = 1.hours
Delayed::Worker.read_ahead = 10
回答1:
It's not possible that delayed job will pick some job and not pick other. Either it will process all job or not process any. If it process any job then your configuration is right.
There might be issue due to Delayed::Worker.destroy_failed_jobs = false this configuration. if your any job fails three times then it will not get deleted from your delayed job table. Because of due to this you might feel that this jobs not get processed.
Try debug your delayed job code with puts.
You can also try https://github.com/resque/resque-scheduler this will provide visual way to watch delayed jobs.
