Yields:

  • (Execution, nil) —

    The next eligible Execution, or nil if none found, before it is performed.

Returns:

  • (ExecutionResult, nil) —

#reschedule_job(scheduled_at = Time.current) ⇒ void

This method returns an undefined value.

Reschedule a scheduled job so that it executes immediately (or later) by the next available execution thread.

Parameters:

#retry_job ⇒ ActiveJob::Base

Retry a job that has errored and been discarded. This action will create a new Execution record for the job.
