Micronaut R2DBC + jOOQ + Flyway + Testcontainers PoC

This PoC is about integrating jOOQ into Micronaut by using R2DBC with reactive streams/Kotlin coroutines, while Flyway is still able to use JDBC to manage schema migrations.

This example uses:

• Micronaut 3.7.x (with the official micronaut-r2dbc module)
• PostgreSQL 13 (with the official r2dbc-postgresql driver)
• Reactor 3.x.x
• jOOQ 3.17.* (and Etienne Studer's great Gradle plugin for jOOQ)
• Flyway 8.5.x
• Testcontainers (to be able to test the integration E2E)

You can read a detailed explanation about this PoC on my blog: https://akobor.me/posts/wiring-up-micronaut-jooq-flyway-and-testcontainers-with-r2dbc
