A revolutionary ORM for Java and Kotlin with the following main features:

1. Query operations against arbitrarily complex object trees, rather than a simple object. Even recursive queries on self-associative properties are possible.

2. Save operations for arbitrarily complex object treesrather than a simple object.

3. Cache operations for arbitrarily complex object trees, rather than a simple object. And guarantee the consistency between the database and the cache.

4. The internal mechanism avoids the use of reflection and obtains the ultimate performance.

5. Based on immutable data objects. By porting immer, you gain the ability to intuitively “modify” deeply immutable objects.

6. Strongly typed SQL DSL, find problems at compile time, not runtime.

7. Java and Kotlin dual API support, the former ensures that all teams are available, and the latter optimizes the development experience.
