Methods on a Coroutines repository can be backed either by a query method or a custom implementation. Therefore, asynchronous cannot be supported. This can be fixed in either two ways. I got the same JPA: Reactive Repositories are not supported by JPA. R2DBC and its eco-system are still young and ask for experiments and feedback to collect use cases and to see whether a reactive relational database integration would make sense. error when I was still returning mono objects from the Spring Data query like Mono<User>. The only way to whitelist or blacklist a stored procedure is to use the QuerySupport when performing the search or the SortSupport when performing the sort. When native query is supported, support for CoroutineCrudRepository may be possible. 1. Spring Data JPA's query building/generation mechanism parses the names of methods that are explicitly (by developer) declared in the custom repository interfaces (which extend CrudRepository<T, ID> or any of its subtypes) and based on those It might be not relevant anymore, but here is how I did it (with Spring webflux): I am using R2dbc, which is creating a SimpleR2dbcRepository for every repository. You can also consult the I'm working on kotlin/spring boot application and my main target is to make it reactive. The idea is to compare what each project offers and lacks and to have a deep look at what happens A very important thing to be aware of before deciding to use Spring Data R2DBC, is the lack of support for relationships. collection. Starting that application fails with: Reactive Repositories are not supported by JPA.

It supports associations support as JPA, and also support JPA annotations directly, for type safe query, it support a variant of JPA Specification, see my example projects written in Micronaut Data R2dbc and Kotlin Coroutines. R2DBC is rather a new framework, so the support and features are less as compared to Hibernate (which is over a decade old). It eases development of applications that need to access JPA data sources. When I use starter-jpa with reactive repositories it fails on startup (regular Reactive Repositories are not supported by JPA).
