Cassandra Schema Guard

A schema registry, validated CQL builder, DDL generator, and migration differ for Apache Cassandra. Version 2.2.0 (stable, released 2024). Define your schema in JSON; all CQL statements are validated against it at build time, catching errors like missing columns or invalid primary key updates before deployment. Differentiators: build-time validation (not runtime), CQL builder that enforces schema correctness, and migration diffing for safe schema evolution. Requires Node.js >=18.0.0.
