Hi @nicola007b I tried the same thing as you and swapped out scala PriorityQueue with the java.util.PriorityQueue, but I then ran into the same serialization error. Could this new issue...

@Itfly I used IndexedSeq instead of Seq/List. Seq are a special cases of iterable and got the same error. List worked too but thought IndexedSeq may give better performance.

no need to modify TopNQueue

@nicola007b doing some tests and will PR soon

Sorry for the delay everyone. I finally got a chance to make the PR.

This appears to be a dead project 😔

Hi @namitk! Thank you for you reply! I just made a PR
