> There should be a helper method to make it easier to register Avro specific record classes.
This will be the most common type that needs to be registered. The code would look something
like:
> {code:java}
> public class AvroHelper {
>     public static void registerAvro(Pipeline p, Class<? extends SpecificRecordBase>
clazz) {
>         p.getCoderRegistry().registerCoder(clazz, new CoderFactory() {
>             @Override
>             public Coder<?> create(List<? extends Coder<?>> componentCoders)
{
>                 return AvroCoder.of(clazz);
>             }
>             @Override
>             public List<Object> getInstanceComponents(Object value) {
>                 return null;
>             }
>         });
>     }
> }
> {code}
> With usage:
> {code:java}
>         Pipeline p = Pipeline.create(options);
>         
>         AvroHelper.registerAvro(p, LogEntry.class);
> {code}
