requery is a lightweight ORM and SQL query generator for Java, Kotlin, and Android that maps annotated entities to relational databases via JDBC. It supports a type-safe DSL for queries, relationships, RxJava observables, and code generation from abstract classes, interfaces, or immutable types.

Use cases

• persist Java objects to SQLite on Android
• generate type-safe SQL queries from annotated entities
• use RxJava observables for database queries
• map Kotlin data classes to a MySQL or Postgres database
• replace heavy ORMs with a lightweight persistence layer
• generate entity classes from interfaces or AutoValue types

When to choose

• you want compile-time code generation instead of runtime reflection
• you need reactive database access with RxJava or Java 8 streams
• you are building an Android app with SQLite persistence
• you prefer a type-safe DSL over raw SQL strings

When to avoid

• you need a mature, actively developed ORM with a large ecosystem
• you want NoSQL or non-relational persistence
• your project uses newer Java features beyond the library's supported baseline
• you need advanced ORM features like multi-tenant caching or sharding
