If I do ```Observable.fromIterable(list).flatMap{ ...

# rx

If I do

Observable.fromIterable(list).flatMap{ fetchItem(item) }

does every item get fetched in parallel?

[ashishkrishnan]

Can flatMap be replaced by an concatMap { } if fetchItem is async?

[abdellah]

concatMap prevents simultaneous execution .. so it dependent on the requirement to choose between concatMap or flatMap
