Hi all, I'd like to use an octree data structure in order to simplify several computations in a big data set. I've been wondering if Spark has any built-in options for such structures (the only thing I could find is the DecisionTree), specially if they make use of RDDs.
I've also been exploring the possibility of using key-value pairs to simulate a tree's structure within an RDD, but this makes the program a lot harder to understand and limits my options when processing the data. Any advice is very welcome, thanks in advance. Regards, Silvina
