## What it is
A Ruby gem extending ActiveJob that makes long-running background jobs interruptible and resumable via cursor-based checkpointing. Developed at Shopify, it lets jobs safely survive deploys, worker restarts, and infrastructure disruptions without losing progress.

## Use cases
- resume background jobs after deploys or restarts
- process millions of ActiveRecord records in a job without losing progress
- make long-running ActiveJob jobs interruptible and resumable
- safely handle worker restarts and pod evictions during batch processing
- checkpoint job progress when iterating over database relations
- backfill or migrate large datasets in background jobs

## When to choose
- you run long-running background jobs on Rails/ActiveJob that risk being interrupted by deploys or infrastructure restarts
- you need resumable iteration over large ActiveRecord relations or batches
- you operate in cloud environments where workers can be evicted at any time

## When to avoid
- your jobs are short-lived and rarely interrupted
- you don't use Rails ActiveJob or a Ruby backend
- you need a general-purpose job scheduler or queue rather than an iteration extension
