Hi all, We have a couple of Python load tests running on Flink in which we are testing the performance of ParDo, GroupByKey, CoGroupByKey and Combine operations.
Recently, I've discovered that the runtime of all those tests rose up significantly. It happened between the 6th and 7th of December (the tests are running daily). Here are the dashboards where you can see the results: https://apache-beam-testing.appspot.com/explore?dashboard=5649695233802240 https://apache-beam-testing.appspot.com/explore?dashboard=5763764733345792 https://apache-beam-testing.appspot.com/explore?dashboard=5698549949923328 https://apache-beam-testing.appspot.com/explore?dashboard=5678187241537536 I've seen in that period we submitted some changes to the core, including Read transform. Do you think this might have influenced the results? Thanks, Kamil
