Add support for R2DBC

[jabrena]

Good afternoon,

I would like to know if exist any plan to provide a R2DBC starter that is shipped by Spring Boot itself. Currently, if a project requires the dependency R2DBC, it appears as Experimental in
https://start.spring.io/

Does exist any plan to change the status?

Many thanks in advance

As far as I know, r2dbc is scheduled to be integrated to the Spring Data release train with Neumann (next major release). When that's the case, it will no longer be experimental and we can take it from there.

Going forward, please ask questions on ou Gitter channel or StackOverflow.

Looking at the issue tracker, we don't have an issue to track the integration of R2DBC here so we can just as well reuse this issue. I'll update the title to make that clear.

We've discussed this one a bit today and we're going to do our best to implement this for 2.3. We're going to use a separate namespace, with support for Flyway and Liquibase only, creating a "local" DataSource for the purpose of the migration.

We should also upgrade @AutoConfigureTestDatabase to swap the ConnectionFactory if possible.

The work that has been done in https://github.com/spring-projects-experimental/spring-boot-r2dbc should help us significantly.
