> Hi,
> We allow customising the {{batch_size}} when streaming to BigQuery but the
> batch duration (used by {{GroupIntoBatches}}) is set to
> {{DEFAULT_BATCH_BUFFERING_DURATION_LIMIT_SEC}} (0.2)
> I'd like to add the option to specify the batch duration to allow better
> batching for scenarios with little data throughput.
> It will use the {{triggering_frequency}} param already used when doing batch
> file loads
