In the c++ client implementation,Why is object data acquired from the metadta?

Describe your problem

In the c++ client, get_objet is based on get_metadata, and the object is acquired from the buffer section of the metadata, which
contradicts the statement in the document that:

Vineyard represents all kinds of data as vineyard objects, for any vineyard object, it consists of two parts:

A set of blobs where the payload of the data lives in;

A hierarchical meta tree that describes the type, layout, and properties of the data.

The decoupling design of data payload and data layout brings three benefits:

it suggests that the metadata and payload are stored separately,

metadata and payload are still stored in different places. Although in the client-side, object are acquired from the metadata, they are stored in a separate place in the server, metadata are stored in the metastored, and payloads are stored through the Apache-Array.

which contradicts the statement in the document that:

Actually get includes two part: get_metadata(), then get_buffers() that involves in the returned metadata.
