If you add par then you will get a parallel collection and operations on it will be processed in parallel. To convert back to a normal collection call a toList.

So your code would look like:

a.par.map(tup => tup._1 + tup._2).toList

Also, check the documentation.

So your code would look like:

Or a .seq to get a Sequential Collection (the opposite of a Parallel Collection).

a.par.map(tup => tup._1 + tup._2).seq

Also, check the documentation.

If you add par then you will get a ParSeq convert back to a normal collection with a toList.

So your code would look like:

a.par.map(tup => tup._1 + tup._2).toList
