> 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
> Priority: Minor
>
> 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.
