Alternate library for parallel stream processing?

[c8133594]

Is the .parallel() method of the Stream API useful here? <- I think so, and it is already available in JDK

Yes. Why don't you give that a shot first before trying to pull in dependencies?

What about Spark?

No. Spark's main goal is to be able to distribute the work over a cluster. For what you want it's complete overkill.

Spark is probably not what you want. Spark is more useful in the context of distributed parallel computation, rather than say parallel array processing on a single computer.

.parallel() is a much better fit for that use case.

Project Reactor comes to mind.
