ROM-RB 4.0 IS COMING
summary
ROM 4.0 is available as 4.0 beta1 and ships a regrouping of features: relations built on Sequel, schema inference that keeps attribute types for any projection, runtime-generated structs with custom namespaces and strict missing-attribute errors, and a pluginized change sets gem for validated transforms and nested creates. It adds cross-database associations, custom mappers and a powerful SQL DSL; microbenchmarks show it often beats ActiveRecord on large reads/writes (thousands of rows), and teams already use it in production.
