Kirill Kozlov updated BEAM-9358: -------------------------------- Description: There is a drastic decrease in Megabytes/second write speeds (from ~50 to ~5) [1], as well as 10x increase in runtime [2] for python BigQueryIO in the PerfKit dashboard. Seems to be fairly recent, started on the Feb 20th and continued on the Feb 21st. Maybe a flake, but still worth investigating.
