Reference/es_mbn
struct es_mbn is an opaque data structure representing a database node. A node is a set of rows or tuples within a database. The set of fields that constitute each row or tuple is described by a database class.
Each row of a node may contain fields that reference other nodes. In this way, each row may be considered to form part of a hierarchical or tree-like structure.
Different rows within one or more nodes of the same class, may refer to the same child node instance. This can be convenient for efficiently modeling many-to-many relationships.
