[jira] [Created] (BEAM-9358) BigQueryIO potential write speed regression

Kirill Kozlov created BEAM-9358:
-----------------------------------

             Summary: BigQueryIO potential write speed regression
                 Key: BEAM-9358
                 URL: https://issues.apache.org/jira/browse/BEAM-9358
             Project: Beam
          Issue Type: Task
          Components: io-py-gcp
    Affects Versions: 2.19.0
            Reporter: Kirill Kozlov


There is a drastic decrease in Megabytes/second write speeds (from ~50 to ~5), as well as 10x increase in runtime [2] for python BigQueryIO in the PerfKit dashboard [1].

Seems to be fairly recent, started on the Feb 20th and continued on the Feb 21st. Maybe a flake, but still worth investigating.
