关于数据 block

看到数据格式是block 如下所示，
{
"node_id": "顶点编号，int",
"node_type": "顶点类型，int",
"node_weight": "顶点权重，float",
"neighbor": {"边类型": {"邻居id": "权重", "...": "..."}, "...": "..."},
"uint64_feature": {"属性编号": ["int", "..."], "...": "..."},
"float_feature": {"属性编号": ["float", "..."], "...": "..."},
"binary_feature": {"属性编号": "string", "...": "..."},
"edge":[{
"src_id": "起点id, int",
"dst_id": "终点id, int",
"edge_type": "边类型, int",
"weight": "边权重, float",
"uint64_feature": {"属性编号": ["int", "..."], "...": ["int", "..."]},
"float_feature": {"属性编号": ["float", "..."], "...": ["float", "..."]},
"binary_feature": {"属性编号": "string", "...": "..."}
}, "..."]
}

请问一下是否支持自定义block，也就是不使用block中的所有键值对，如下：
{
"node_id": "顶点编号，int",
"node_type": "顶点类型，int",
"neighbor": {[]},
"edge":[{
"src_id": "起点id, int",
"dst_id": "终点id, int",

}, "..."]
}

The issue only provides example block structures and names no source files or tests. Start by locating the code that parses or validates node and edge blocks, then determine whether omitted fields can be accepted; done means the reduced block example is supported without requiring the unused keys.
