Hibernate Reactive is a reactive API for Hibernate ORM, supporting non-blocking database drivers and a reactive style of interaction with the database.

The central APIs are defined as inner interfaces of

• Mutiny, for programs using Mutiny reactive streams, and
• Stage, for programs using Java's CompletionStage.

An instance of Mutiny.SessionFactory or Stage.SessionFactory may be obtained by calling EntityManagerFactory.unwrap(Class).

The public API is organized into the following packages:

org.hibernate.reactive.mutiny	—	APIs specific to usage with Mutiny reactive streams
org.hibernate.reactive.stage	—	APIs specific to usage with CompletionStage
org.hibernate.reactive.common	—	APIs common to both kinds of reactive stream
org.hibernate.reactive.id	—	SPI for plugin custom identifier generation
org.hibernate.reactive.pool	—	SPI for plugin custom connection pooling
org.hibernate.reactive.vertx	—	SPI for plugin custom integration with Vert.x

SPIs are implemented as Hibernate services.

Packages not listed above are considered non-public and are subject to change without notice.
