Hibernate validator and reactive

[robp94]

Is it somehow possible to have a custom validator with a blocking call, like to a web service, without blocking?

The interface ConstraintValidator does not have a Uni/CompletableFuture return type, there seems to be no reactive alternative.
If you use it anyway on reactive Methods with the @Valid annotation, it fails because it is blocking. The only ugly why I came up with is with using @Blocking annotation or calling it by myself and using for example the default worker pool of Mutiny.

Is there another option without blocking? Are there maybe plans to add a reactive version of the validator?

Short answer: it's complicated, and Hibernate Validator/Bean Validation was not built for this.

As to future plans, we'll consider merging pull requests as always, as long as they take into account the constraints mentioned in the issue.
