> Project: Beam
> Issue Type: Bug

> Apache Beam [1] is a unified and portable programming model for data
> processing jobs (pipelines). The Beam model [2, 3, 4] has rich mechanisms to
> process endless streams of events.
> Nexmark [5] is a benchmark for streaming jobs, basically a set of jobs
> (queries) to test different use cases of the execution system. Beam
> implemented Nexmark for Java [6, 7] and it has been succesfully used to
> improve the features of multiple Beam runners and discover performance
> regressions.
> Thanks to the work on portability [8] we can now run Beam pipelines on top of
> open source systems like Apache Spark [9] and Apache Flink [10]. The goal of
> this issue/project is to implement the Nexmark queries on Python and
> configure them to run on our CI on top of open source systems like Apache
> Spark and Apache Flink. The goal is that it helps the project to track and
> improve the evolution of portable open source runners and our python
> implementation as we do for Java.
> Because of the time constraints of GSoC we will adjust the goals (sub-tasks)
> depending on progress.
