Commits on Aug 14, 2013

  1. Add index on delayed_jobs (locked_at, locked_by) 

    This index avoids an increasingly growing performance penalty when delayed_jobs table tends to
grow bigger.

  2. Add index on delayed_jobs (run_at, failed_at, priority) 

    When lots of failed jobs occur, this index gives huge performance benefit on high loads with big
delayed_jobs table.
