## What it is
MyBatis-Plus-Join is a Java library that extends MyBatis-Plus with multi-table join query support in a MyBatis-Plus style. It provides lambda-based wrappers for left join, right join, and other join operations while remaining non-invasive to existing projects.

## Use cases
- perform left join queries with mybatis-plus
- write multi-table joins using lambda wrappers
- join tables without writing XML SQL
- select columns from joined entities type-safely
- map one-to-one and one-to-many join results
- extend existing mybatis-plus project with join support

## When to choose
- you already use MyBatis-Plus and need join queries
- you want type-safe lambda-based multi-table queries
- you want to avoid hand-writing join SQL in XML mappers
- you need logical delete, type handler, and alias support in joins

## When to avoid
- you don't use MyBatis-Plus or MyBatis
- you prefer writing raw SQL or use a full ORM like Hibernate
- your queries are simple single-table operations already handled by MyBatis-Plus
