Neville Li updated BEAM-2658:
-----------------------------
Description:
{code}
import com.google.protobuf.Timestamp;
import org.apache.beam.sdk.Pipeline;
import org.apache.beam.sdk.coders.CannotProvideCoderException;
import org.apache.beam.sdk.coders.Coder;
import org.apache.beam.sdk.options.PipelineOptions;
import org.apache.beam.sdk.options.PipelineOptionsFactory;
public class CoderTest {
public static void main(String[] args) throws CannotProvideCoderException {
PipelineOptions options = PipelineOptionsFactory.fromArgs(args).create();
Pipeline pipeline = Pipeline.create(options);
Coder<Timestamp> coder =
pipeline.getCoderRegistry().getCoder(Timestamp.class);
// class org.apache.beam.sdk.coders.SerializableCoder
System.out.println(coder.getClass());
}
}
{code}
Right now we're sorting {{CoderProviderRegistrar}}s by canonical name but
{{SerializableCoderProvider}} should be added last as a fallback if there're
other {{CoderProvider}}s that support the same type.
{code}
Set<CoderProviderRegistrar> registrars =
Sets.newTreeSet(ObjectsClassComparator.INSTANCE);
{code}
