public record SqlMapping(String name, String connectorType, List<SqlMapping.Column> columns, Map<String,String> options)
extends Record

Catalog metadata for a SQL mapping.

The current SQL engine executes against LoomCache data structures rather than an external planner. Mappings provide the catalog surface needed by DDL and future SHOW/EXPLAIN work while keeping connector-specific behavior explicit.
