Hi Team,
I was looking for a Spark window function example on documentation.
For example, I could the function definition and params are explained
nicely here:
https://spark.apache.org/docs/latest/api/python/pyspark.sql.html#pyspark.sql.Window.rowsBetween
and this is the source which is available since spark version 2.1:
https://spark.apache.org/docs/latest/api/python/_modules/pyspark/sql/window.html#Window.rowsBetween
But I couldn't find an example which helps to understand How it works.
Although, while browsing the GitHub code I have found some example here:
https://github.com/apache/spark/blob/master/python/pyspark/sql/window.py#L83
which I couldn't find on the spark official doc page. Where and how this
example is linked with the official spark documentation.
If such examples are not available, Could you please share the process on
how I can contribute examples to the spark documentation.
Regards,
Neeraj
