I have struggled with this as well and I believe I understand the problem now. Just as an aside, you can use scala - Redis on spark: variable pipeline in class ... for a code paste bin and it supports boost

You would need to add a margin or something somewhere though

Bringing this question up to date by providing this answer. A robust implementation would probably define these
