Is it possible to use both Spring Data R2DBC and Spring Data JPA in a single Spring boot application?

Question

I have an application which is using Spring data JPA and hibernate envers for db auditing. Since R2DBC doesn\'t support auditing yet, is it possible to use combination of b

Answer 1

1. Spring provided simple Auditing via @EnableR2dbcAuditing, check my example.

2. Mix JPA in a reactive application is also possible, I have an example to demo run JPA in a reactive application, but not added r2dbc in it.

3. For your plan, a better solution is applying the cqrs pattern on the database topology, use database cluster for your application.

   • JPA for applying changes, use the main/master database to accept the modification, and sync changes to the secondary/slave database.
   • r2dbc for queries as you expected, use the secondary/slave database to query.
   • use a gateway at the front for the query and command service.

Update: I have created a sample to demo JPA and R2dbc coexistence in a single webflux application. But I do not suggest using it in real-world applications. Consider the 3rd solution above if you really need it.
