------------------------------------
Summary: Allow Failsafe Handling of BigQuery Streaming Writes
Key: BEAM-11006
URL: https://issues.apache.org/jira/browse/BEAM-11006
Project: Beam
Issue Type: Improvement
Components: extensions-java-gcp
Reporter: Dylan Hercher
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.
