Work Description: dhercher opened a new pull request #13055:
URL: https://github.com/apache/beam/pull/13055
Implementing a new function to allow BigQueryIO write to have customized Failsafe handling for Streaming Writes.
Adding a new withFailsafeFormatFunction() which formats the original PCollection value into a raw TableRow (which does not have to match the TableRow written to BigQuery.
PCollection<FailsafeElement<String, TableRow>> can write the TableRow to BigQuery, but restore the original payload on an exception.

> To allow handling of a generic failsafe (of any type) would allow a dead letter queue to retain the original source data rather than the cleaned version and could be more easily understood and re-processed.
>
> The BigQueryIO.Write currently supports `withFormatFunction` which allows for a serializable function to be applied to each datapoint -> TableRow. Ideally that same source value could be converted with a separate function:
> `withFailsafeFormatFunction` taken (InputT -> TableRow) or possibly (InputT -> OutputT), though the backwards compatibility of OutputT is more difficult.
