Extends the JUDO DAO RDBMS query translation layer with custom mappers, translators, and join strategies.
The judo-runtime:custom-queries skill provides a comprehensive framework for extending the JUDO Core runtime's database query generation capabilities. It enables developers to implement custom MapperFactory and RdbmsMapper classes, allowing for the precise translation of unique query elements into valid SQL. This skill is particularly valuable when standard mappings are insufficient, such as when integrating specialized join logic, handling custom expressions, or optimizing SQL generation for complex schemas within the JUDO framework.
