[jira] [Updated] (BEAM-10233) Return error message/information with existing FAILED_ROW data from BigQueryWriteFn (Python SDK)

> Key: BEAM-10233
> URL: https://issues.apache.org/jira/browse/BEAM-10233
> Project: Beam
> Issue Type: Improvement
> Components: io-py-gcp
> Reporter: Tom Hardman
> Priority: P2
> Labels: stale-P2
>
> A user may call `apache_beam.io.gcp.bigquery.WriteToBigQuery` to write their streamed data to BQ. If any rows fail to write, this will return a tagged pcollection `BigQueryWriteFn.FAILED_ROWS`. This data includes a tuple `(destination_table, failed_row_payload)`.
> My suggestion is to include the error information in the `FAILED_ROWS` pcollection. From the source code we can see that we have access to the error information, e.g. that the row failed because field `id` was `invalid` because `this field is not a record`. I think we should surface this to the user.
> I'm happy to open a PR for this myself (as I've already had to overwrite the original code in several projects), but it looks like we'd need a breaking change by either extending the tuple which would cause unpacking issues in existing code, or by returning a different data structure entirely.
