Jan Peuker commented on BEAM-4096:
----------------------------------
Thanks Eugene, very helpful, I suppose you mean the fact that in
BigQueryIO.Write.expand different PTransforms are created per method. In my
tests using a manually constructed graph (i.e. StaticValueProvider) it worked,
but that's probably because I haven't done enough dynamic testing yet.
> BigQueryIO ValueProvider support for Method and Triggering Frequency
> --------------------------------------------------------------------
>
> Key: BEAM-4096
> URL: https://issues.apache.org/jira/browse/BEAM-4096
> Project: Beam
> Issue Type: Improvement
> Components: io-java-gcp
> Affects Versions: 2.4.0
> Reporter: Ryan McDowell
> Priority: Minor
> Fix For: 2.5.0
>
>
> Enhance BigQueryIO to accept ValueProviders for:
> * withMethod(..)
> * withTriggeringFrequency(..)
> * withNumFileShards(..)
> It would allow Dataflow templates to accept these parameters at runtime
> instead of being hardcoded. This opens up the ability to create Dataflow
> templates which allow users to flip back-and-forth between batch and
> streaming inserts.
