If I understand correctly, what's being used here is the "-wise" suffix,
unrelated to wisdom, which Merriam Webster lists as "adverb combining
form" here (though you
have to scroll down a lot), which is defined as

1 a :in the manner of  * crabwise * fanwise
  b :in the position or direction of  * slantwise * clockwise
2 :with regard to :in respect of * dollarwise

According to that, the right way to write this is "partitionwise join"
(no dash), which means "join in respect of partitions", "join with
regard to partitions".
