Scrooge is a Framework and ORM agnostic Model / record attribute tracker to ensure production Ruby applications only fetch the database content needed to minimize wire traffic and reduce conversion overheads to native Ruby types. An unobtrusive, cluster friendly auto-configuration with a warmup period strategy is supported for production use. It’s not meant to replace or compete with fragment caching, but may compliment an existing caching setup or minimize overheads when caching is not viable.
