Hi,It seems that there is a notable overlap with what Nexmark already does:Nexmark mesures performance and regression by exercising all the Beam model in both batch and streaming modes with several runners. It also computes on synthetic data. Also nexmark is already included as PostCommits in the CI and dashboards.Shall we merge the two?BestEtienneLe lundi 10 septembre 2018 à 12:56 +0200, Łukasz Gajowy a écrit :Hello everyone,thank you for all your comments to the proposal. To sum up:A set of performance tests exercising Core Beam Transforms (ParDo, GroupByKey, CoGroupByKey, Combine) will be implemented for Java and Python SDKs. Those tests will allow to:
- measure performance of the transforms on various runners
- exercise the transforms by creating stressful conditions and big loads using Synthetic Source and Synthetic Step API (delays, keeping cpu busy or asleep, processing large keys and values, performing fanout or reiteration of inputs)
- run both in batch and streaming context
- gather various metrics
- notice regressions by comparing data from consequent Jenkins runsMetrics (runtime, consumed bytes, memory usage, split/bundle count) can be gathered during test invocations. We will start with runtime and leverage Metrics API to collect the other metrics in later phases of development.The tests will be fully configurable through pipeline options and it will be possible to run any custom scenarios manually. However, a representative set of testing scenarios will be run periodically using Jenkins.

I'm bumping this (in case you missed it). Any feedback and questions are welcome!

Thanks for the update, and the abstract looks promising.
Let me take a look on the doc.
