What type of app?

A web UI, maybe a phoenix app, or something simpler.

Basic version: list failed jobs, allow you to retry or delete them.

Toniq.failed_jobs Toniq.retry(job) Toniq.delete(job)

Alternatively (or in addition to snapshotting), Redis can run in append mode. Any time a key changes, an append-only file is updated on disk. In some cases it's acceptable to lose 60 seconds worth of data, in exchange for performance, should there be some hardware or software failure. In some cases such a loss is not acceptable. Redis gives you the option. In chapter 5 we'll see a third option, which is offloading persistence to a slave.

id = redis.hget('users:lookup:email', 'leto@dune.gov')

user = redis.get("users:#{id}")
