> Right now there is no metadata commit API in data stream. Data steam has a
> header request, a data api that can send raw bytes in a streaming manner, and
> a close.
> There is practice that an application can append metadata at the end of the
> stream, and consume then commit the metadata upon the stream close. However,
> this is not official API. Meanwhile, such approach cannot support metadata
> commits before steam close.
> There could be use cases that metadata needs to be committed at specific
> offset, and more than once, before data stream should be close.
