Review comment:
Do we need this encoding/decoding round trip if the query aims to
benchmark against the SDK/runner boundary?

> In portability world, we expect on workers there are runners and SDKs.
> Current Nexmark queries, e.g. Nexmark Query 0, does not stress the boundary
> between runner and SDK.
> So I propose to have Nexmark query 13, which contains a source + GBK + ParDo,
> to stress the boundary between runner and SDK.
