Description
The backfill pods can use several GB of memory (monitoring) because it defaults to 16 queries at a time which starts 16 python subprocesses which then start their own subprocesses in the bq cli. Lowering parallelism should improve this without doing optimizations in bigquery-etl. I think 6 is fine because more would likely be slot constrained. Also setting a resource request to try to trigger scaling and prevent eviction
