Detailed Description

Router job that takes jobs and enqueues them to their proper queues.

This can be used for several things:

  • a) Making multi-job enqueues more robust by atomically enqueueing a single job that pushes the actual jobs (with retry logic)
  • b) Masking the latency of pushing jobs to different queues/wikis
  • c) Low-latency enqueues to push jobs from warm to hot datacenters
