> Allow specifying BigQuery Storage API readOptions at runtime
> ------------------------------------------------------------
>
> Key: BEAM-8023
> URL: https://issues.apache.org/jira/browse/BEAM-8023
> Project: Beam
> Issue Type: Improvement
> Components: io-java-gcp
> Reporter: Jeff Klukas
> Assignee: Kenneth Jung
> Priority: Minor
> Time Spent: 2h 20m
> Remaining Estimate: 0h
>
> We have support in the Java SDK for using the BigQuery Storage API for reads,
> but only the target query or table is supported as a ValueProvider to be
> specified at runtime. AFAICT, there is no reason we can't delay specifying
> readOptions until runtime as well.
> The readOptions are accessed by BigQueryStorageTableSource in getTargetTable;
> I believe that's occurring at runtime, but I'd love for someone with deeper
> BoundedSource knowledge to confirm that.
> I'd advocate for adding new methods
> `TypedRead.withSelectedFields(ValueProvider<List<String>> value)` and
> `TypedRead.withRowRestriction(ValueProvider<String> value)`. The existing
> `withReadOptions` method would then populate the other two as
> StaticValueProviders. Perhaps we'd want to deprecate `withReadOptions` in
> favor or specifying individual read options as separate parameters.
