<!-- Answer -->
To declare both vertices and edges in the same struct with `id:1` in your v2
mapping JSON file, you can include both `vertices` and `edges` as lists within
the same struct. Here's a simple example of how you might define such a struct:
```json
{
"id": "1",
"skip": false,
"input": {
"type": "FILE",
"path": "${store_path}/vertex_and_edge.csv",
"file_filter": {
"extensions": ["*"]
},
"format": "CSV",
"delimiter": ",",
"date_format": "yyyy-MM-dd HH:mm:ss",
"time_zone": "GMT+8",
"skipped_line": {
"regex": "(^#|^//).*|"
},
"compression": "NONE",
"header": ["name", "age", "city", "source_name", "target_name"],
"charset": "UTF-8",
"list_format": {
"start_symbol": "[",
"elem_delimiter": "|",
"end_symbol": "]"
}
},
"vertices": [
{
"label": "person",
"skip": false,
"id": null,
"unfold": false,
"field_mapping": {},
"value_mapping": {},
"selected": [],
"ignored": [],
"null_values": [""],
"update_strategies": {}
}
],
"edges": [
{
"label": "knows",
"skip": false,
"source": ["source_name"],
"unfold_source": false,
"target": ["target_name"],
"unfold_target": false,
"field_mapping": {
"source_name": "name",
"target_name": "name"
},
"value_mapping": {},
"selected": [],
"ignored": [],
"null_values": [""],
"update_strategies": {}
}
]
}
```
In this example, the `input` section is configured to read from a CSV file
that contains both vertex and edge data. The `vertices` list defines the vertex
mapping, while the `edges` list defines the edge mapping. Adjust the
`field_mapping` and other configurations as needed to match your data structure
and requirements
