Retry failed executions without waiting for the next scheduled run #16

Description

@mlopezFC

The problem

A job scheduled for Fridays at 04:00 that fails at 04:00 waits until next Friday. There is no retry, so a transient failure — a database that was briefly unavailable, a network blip — costs a full cycle.

What we have in mind

Retry executions configurable per process, along the lines of what App Engine's cron retry parameters cover:

  • A maximum number of retry attempts
  • A time limit measured from the original scheduled time
  • Backoff between attempts

Both bounds applying together, so a job stops retrying when either is reached.


Opened from our own backlog when this tracker went public. If you need this, say so — comments and concrete use cases are what move something up the list.
