Persisting Relations Across Time and Space
summary
Compares concrete persistence strategies and shows what actually works: PStore atomically commits Ruby objects to a YAML-backed file and supports concurrent read transactions; PostgreSQL provides array and point types to avoid join bloat; document stores like MongoDB support nested documents and client-side dereferencing; Redis maps Ruby objects to native types; graph databases store relations as edges for fast traversals. Demonstrates Candy (transparent Mongo persistence via method_missing) and Ambition (Ruby-shaped querying across adapters) and notes several object-DB efforts still unfinished.
