Jakarta Data is a new specification for persistence in Java, scheduled for release as part of the EE 11 platform. Whereas Jakarta Persistence provides a mature and extremely feature-rich foundation for object/relational mapping solutions like Hibernate, Jakarta Data aims to offer a somewhat simplified programming model, but one which is also suitable for use with non-relational databases.

Hibernate Reactive 1.0.0.Final is the first production-ready release of Hibernate Reactive, the only object-relational mapping solution that supports non-blocking database drivers and a reactive style of interaction with the database.

Hibernate Reactive now supports PostgreSQL, MySQL, MariaDB, Db2, SQL Server, and CockroachDB, and features almost all the functionality of the original Hibernate ORM. Under the hood, Hibernate Reactive uses the Vert.x non-blocking SQL client libraries.

Testing by the Hibernate team shows that use of Hibernate Reactive can, in at least some circumstances, significantly improve performance in situations of high database server load, compared to the use of traditional ORM over JDBC. (However, we must caution that a reactive system isn’t faster than a non-reactive program all or even most of the time!)

Three months have passed since the first announcement, and we’re finally ready to release Hibernate Reactive 1.0.

Hibernate Reactive is a reactive API for Hibernate ORM, which supports non-blocking database clients and reactive programming as a paradigm for interacting with the relational database. This release supports the full feature set of JPA, along with almost the whole feature set of Hibernate ORM core, including an impressive array of features for achieving high performance data access.

Hibernate Reactive 1.0 supports the following databases:
