Review Comment:
> Doesn't `newBuilder(cloudEvent)` automatically merge the attributes (i.e.,
`cloudEventMap`) of `cloudEvent` here? Additionally, is `prop` object redundant
now?

`newBuilder(cloudEvent)`这一步不是会自动合并`cloudEvent`的attributes（即`cloudEventMap`）吗？另外`prop`对象现在是不是多余的？
@pandaapo Here, it is guaranteed that if there are identical properties
between the returned message and the consumed message, the properties of the
consumed message will be used. At the same time, I compared the version before
optimization. It is also a similar operation. If the properties do not need to
be overwritten, this step is not required. I keep it consistent with the
version before GRPC optimization.
