Request For Support of N-Tuples and N-Functions

[Léonard Schneider]

Hi,

As reactor is FP oriented, I believe it would be useful to be able to use N-Tuples and N-Functions (which should really be part of JDK IMO). You have an example of that in JOOL (https://github.com/jOOQ/jOOL). This would allow to write async scatter-gather patterns in an elegant way, e.g.

Mono.just(1)

  .and(Mono.just("x"))

  .and(Mono.just(true))

  .flatMap((x, y, z) -> myFunction(x, y, z))

  .single();

BR,

Leo

You can post that idea on our issue tracker it has been requested actually by one of our power user (https://github.com/cloudfoundry/cf-java-client) so it could in fact be a valid addOn. In general adding more noise to Flux could be a concern, the RS spec only allows one argument passing method with onNext and Tuple aims to relieve a bit the user of this constraint.

It's also a good idea for language extensions like https://github.com/reactor/reactor-kotlin and https://sinwe.github.io/reactor-core-scala/.
