Description

When field names of an object are used in SQL, text or other kind of queries, object, that owns a field, is fully deserialized.
This is bad from performance perspective.

The task is to support peer field deserialization by looking it up in a marshalled byte array and unmarshalling it from a concrete offset with OptimizedMarshaller later.
