> BigQuery IO - Storage API (DIRECT_READ): Fraction consumed decreasing between
> responses
> ---------------------------------------------------------------------------------------
>
> Key: BEAM-11061
> URL: https://issues.apache.org/jira/browse/BEAM-11061
> Project: Beam
> Issue Type: Bug
> Components: io-java-gcp
> Affects Versions: 2.23.0
> Reporter: Jonas Grabber
> Priority: P3
>
> When reading a couple of million rows (and above 100 Gigabytes) from BigQuery
> Storage (DIRECT_READ) with Dataflow and above 8 vCPUs (4x n1-standard-4) the
> attached exception is thrown about once per vCPU.
> The issue seems to be that the value of fraction_consumed in the
> [StreamStatus|https://cloud.google.com/bigquery/docs/reference/storage/rpc/google.cloud.bigquery.storage.v1beta1#streamstatus]
> object returned from the Storage API decreased between responses.
> I tested this repeatedly with varying amounts of input data, number of
> workers and machine types and was able to reproduce the issue repeatedly with
> different configurations above 4 -8- vCPUs used (2, 4, 16, 32, 128 and,
> n1-highmem-4, n1-standard-4, n1-standard-8, and n1-standard-16).
> So far Jobs with 4 -8- vCPUs ran fine. (Update: Latest job with 4 vCPUs, 2x
> n1-highmem-4, also threw the exception).
