Has PRDD (partial-update) been included in any version of the Apache spark?

Question

I am referring to below IEEE paper :

https://ieeexplore.ieee.org/document/7973685/authors#authors

Here by PRDD they mean Partial-update RDD.

I tried to search same but couldn't find any references in spark documentation.

Hence, asking here if it has been included in any of the version of the spark.

Answer 1

It has not been included in any official Spark build.
