When should I use custom mappers instead of built-in ones?

Use custom mappers when you need to handle domain-specific query elements, specialized join strategies, or vendor-specific SQL functions not covered by standard JUDO mappers.

Can I use this skill to optimize database performance?

Yes, by implementing custom join processors like SubSelectJoinProcessor or CustomJoinProcessor, you can optimize how the database executes complex relationship queries.

What is the primary purpose of this skill?

This skill provides guidance for extending the JUDO DAO RDBMS layer, allowing developers to create custom SQL translation logic for unique query elements.

How do I register my custom mappers in JUDO?

Custom mappers are registered via Guice modules by adding a binding to the MapperFactory multibinder, ensuring they are discovered by the RdbmsBuilder.

Extends the JUDO DAO RDBMS query translation layer with custom mappers, translators, and join strategies.

关于

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.
