> Determine Spanner schema at pipeline construction in cross-language SpannerIO
> -----------------------------------------------------------------------------

> Key: BEAM-10851
> URL: https://issues.apache.org/jira/browse/BEAM-10851
> Project: Beam
> Issue Type: Improvement
> Components: cross-language, io-java-gcp, io-py-gcp
> Reporter: Piotr Szuberski
> Priority: P2
> Labels: stale-P2
>
> For now Spanner's cross-language transform requires to get Beam Schema. It
> should be possible to determine the schema otherwise.
> One solution would be to execute query with spanner client and then translate
> spanner schema to beam schema. But this is very poor solution as the query
> would be executed twice.
> Look for it at SpannerTransformRegistrar.ReadBuilder
