Job Format

Sidekiq serializes jobs to Redis in JSON format.

Job

At bare minimum, a job requires three fields:

{
  "class": "SomeWorker",
  "jid": <12-byte random number as 24 char hex string>,
  "args": [1, "arg", true],
}

args is splatted onto the worker class's perform method.

Retries

Sidekiq's retry feature adds several elements to the job payload:

• queue - the queue to use when retrying
• retry_count - number of times we've retried so far
• error_message - the exception message
• error_class - the exception class
• error_backtrace - some or all of the exception's backtrace, optional
• failed_at - the first time the job failed
• retried_at - the last time the job failed
