> Key: BEAM-7732
> URL: https://issues.apache.org/jira/browse/BEAM-7732
> Project: Beam
> Issue Type: Improvement
> Components: io-java-gcp
> Affects Versions: 2.12.0, 2.13.0
> Reporter: Niel Markwick
> Priority: Minor

> Beam hides the [SpannerOptions|https://github.com/googleapis/google-cloud-java/blob/master/google-cloud-clients/google-cloud-spanner/src/main/java/com/google/cloud/spanner/SpannerOptions.java] object behind a [SpannerConfig|https://github.com/apache/beam/blob/master/sdks/java/io/google-cloud-platform/src/main/java/org/apache/beam/sdk/io/gcp/spanner/SpannerConfig.java] object because the SpannerOptions object is not serializable.
> This means that the only options that can be set are those that can be specified in SpannerConfig - limited to host, project, instance, database.
> Suggestion: add the possibility to set a SpannerOptionsFactory in SpannerConfig:
> {code:java}
> public interface SpannerOptionsFactory extends Serializable {
> public SpannerOptions create();
> }
> {code}
> This would allow the user use this factory class to specify custom SpannerOptions before they are passed onto the connectToSpanner() method;
> connectToSpanner() would then become:
> {code:java}
> public SpannerAccessor connectToSpanner() {
>
> SpannerOptions.Builder builder = spannerOptionsFactory.create().toBuilder();
> // rest of connectToSpanner follows, setting project, host, etc.
> {code}
>
