It's not going to be as fast as having a service pre-defined with the requisite repository injected into it, but that would require you to create the repositories and services for each entity. Use CTEs and recursive CTEs; Use modification CTEs aka DML in CTEs I was not able to find any similar mechanism to support entity inheritance with spring data r2dbc.

At least not yet. transactionManagerRef - Configures the name of the {@link PlatformTransactionManager} bean definition to be used to create repositories discovered through this annotation. Introducing additional wrapper types would pollute the domain model for non-blocking, lazy loading. jpa and reactive don't work together afaik. The way it does all of that is by using a design model, a database Spring Data JDBC aims to be much simpler conceptually than JPA by not implementing popular patterns like lazy loading, caching, dirty context, sessions. You may want to look at Spring Data R2DBC. Here's how you can use JPA with Spring WebFlux using reactive repositories: Dynamic filtering for the entities with JPA Static metamodel; in reactive mode, you have a warning during project generation to inform user filtering will not work : referenced by @smaestri spring R2DBC does not support (built inside repository) & ColumnConverter (component available inside repository) No filtering support on the non Spring Data JPA does not support the Spring WebFlux. 1. A simple if statement is not the solution, since it requires to use the correct reactive repository with the corresponding reactive configuration, reactive template, etc On the repository layer, very straightforward, not even using any custom queries. See the store-specific documentation for more details on reactive support. You can review how R2DBC methods are translated to PostgreSQL queries here. The reactive Repository interface is available in version 3. Adding a few methods that turn a blocking API into a reactive one unfortunately doesn't do the trick. Beyond that, it activates persistence exception translation for all beans annotated with @Repository, to let exceptions being thrown by the JPA persistence providers be converted into Spring’s DataAccessException hierarchy.
