MIGRATING TO CLOJURE. SO MUCH FN
summary
Gradual migration replaces a Rails monolith serving five million monthly visitors with Clojure widgets that are two functions widgets as fetch+view, run alongside Ruby in a single JVM with a thin data-translation layer, and render independently so immutability lets a simple swap from map to pmap parallel rendering speed up pages. Templates convert HTML to data via nlife, live-editing uses nREPL over TCP so production fixes and interactive development happen in-process, and infrastructure dropped from ~50–60 Ruby servers to about 12 JVMs while traffic grew.
