Google Cloud Dataflow ships with a set of standard coders, which is great. However, none of them support nulls (inherently since java.io.DataOutput does not support nulls).
Google Cloud Dataflow附带了一组标准编码器，非常棒。但是，它们都不支持空值（因为java.io.DataOutput不支持空值）。
Just wondering, should one decorate each of the available coders, or maybe this had already been done somewhere?
只是想知道，是否应该装饰每个可用的编码器，或者这可能已经在某处完成了？
Thanks,
谢谢，

Correct. The default coders for primitive types don't support null. AvroCoder can support nulls if using @Nullable or Unions.
正确。原始类型的默认编码器不支持null。如果使用@Nullable或Unions，AvroCoder可以支持空值。
We can look into adding a coder that supports null. I've filed a feature request. Thanks!
我们可以考虑添加一个支持null的编码器。我已经提交了功能请求。谢谢！
