Minimal example

see issue spring-projects/spring-data-commons#2503

docker-compose up

See DemoApplication.kt for code.

Then go to these browser URIs in the following order:

GET localhost:8080          // => []
GET localhost:8080/x/add    // => {"id":1,"name":"x"}
GET localhost:8080          // => [{"id":1,"name":"x"}]
GET localhost:8080/x/delete // => "ok"
GET localhost:8080          // => [{"id":1,"name":"x"}]

Note that the delete is not executed.

Then add suspend to the delete method in the repository, restart the application and do:

GET localhost:8080/x/delete // => "ok"
GET localhost:8080          // => []
