Hi again.
I have another question about weak consistencyLevel.
according to the manual, s2graph has tow types of consistency level:strong, weak
I want to get several edges between two vertices, so, I set a weak consistency
level.
after setting, I tried to get edges, but it returned only one edge like
‘strong’ level.
What is wrong with my query?
here is my setting and queries.
————————————————————————————————————————————
1. create a service
curl -XPOST localhost:9000/graphs/createService -H 'Content-Type:
Application/json' -d '
{"serviceName": "KakaoFavorites", "compressionAlgorithm" : "gz"}
‘
2. create a level
curl -XPOST localhost:9000/graphs/createLabel -H 'Content-Type:
Application/json' -d '
{
"label": "s2graph_label_test_weak",
"srcServiceName": "KakaoFavorites",
"srcColumnName": "userName",
"srcColumnType": "string",
"tgtServiceName": "KakaoFavorites",
"tgtColumnName": "userName",
"tgtColumnType": "string",
"isDirected": "true",
"indices": [],
"props": [
{"name": "time", "defaultValue": 0, "dataType": "long"}
],
"consistencyLevel": "weak"
}
‘
3. insert edges with meta data
curl -XPOST localhost:9000/graphs/edges/insert -H 'Content-Type:
Application/json' -d'
[
{"timestamp": 1, "from": 101, "to": 10, "label": "s2graph_label_test_weak",
"props": {"time": 0}},
{"timestamp": 2, "from": 101, "to": 10, "label": "s2graph_label_test_weak",
"props": {"time": -10}},
{"timestamp": 3, "from": 101, "to": 10, "label": "s2graph_label_test_weak",
"props": {"time": -30}}
]
'
4. query id “101” and direction “out”
curl -XPOST localhost:9000/graphs/getEdges -H 'Content-Type: Application/json'
-d '
{
"srcVertices": [{"serviceName": "KakaoFavorites", "columnName": "userName",
"id":"101"}],
"steps": [
{"step": [{"label": "s2graph_label_test_weak", "direction": "out",
"offset": 0, "limit": 100}]}
]
}
‘
5. it returns like this
