CompositeFuture all vs join

[javadevmtl]

http://vertx.io/docs/vertx-core/java/#_concurrent_composition

What is the difference? Seems very similar.

Ok I see the difference

all

---------

- Handler will get called if and only all futures succeeded and completed.

- Handler will get called if and any one future failed and completed. 

join

---------

- Handler will only get called only if all futures completed. Status will be success if all futures succeeded or fail if any one failed.

I guess we can think of ALL as fail fast and JOIN as fail safe. Maybe not the best analogy but hey...
