Aster Functions equivalent in spark : cfilter, npath and sessionize

[didier vila <sp...@hotmail.com>]

Good morning all, 
I am interesting to know if there is some Aster equivalent functions in Spark . 
In particular, I would like to sesionize or create some sessions based.
I would to create some npath or sequence based based on a specific pattern.https://aster-community.teradata.com/docs/DOC-1544
I would like to derive some affinitiehttps://aster-community.teradata.com/docs/DOC-1552
I am python user of Spark and I would to demonstrate that Spark is  a very good candidate instead of Aster ( Aster will run in Hadoop soon). 
do you have any Spark python code  to demonstrate my colleague that Spark is the best options ? 
thanks for this.

Some of the Aster functions you are referring to can be done using Window
functions in SparkSQL:
