Parallel Streams Done Right

Downsides of Parallel Streams

Parallel collection processing using Stream API can be as easy as:

Java

 

x

 

1

List<Integer> result = list.parallelStream()

2

  .map(toSomething())

3

  .collect(Collectors.toList());

Unfortunately, we can't choose an execution facility, define per-instance parallelism, or avoid blocking the calling thread.
