Description

following is steps to reproduce bug.

1. create service.

   curl -XPOST localhost:9000/graphs/createService -H 'Content-Type: Application/json' -d '
   {"serviceName": "s2graph-test"}
   '
   

2. create label.

   curl -XPOST alpha-s2graph.daumkakao.io:9000/graphs/createLabel -H 'Content-Type: Application/json' -d '
   {
       "label": "friend",
       "srcServiceName": "s2graph-test",
       "srcColumnName": "user_id",
       "srcColumnType": "string",
       "tgtServiceName": "s2graph-test",
       "tgtColumnName": "user_id",
       "tgtColumnType": "string",
       "indices": [],
       "props": [],
       "serviceName": "s2graph-test",
       "consistencyLevel": "strong"
   }
   '
   

3. insert test data.

   curl -XPOST localhost:9000/graphs/edges/insert -H 'Content-Type: Application/json' -d '
   [
   {"timestamp": 1451374817379, "from": "4c9343846613f66931000007", "to": "4cc8ad306899f56692000004", "label": "friend"}
   ]
   '
   

4. delete above relation.

   curl -XPOST localhost:9000/graphs/edges/delete -H 'Content-Type: Application/json' -d '
   [
   {"timestamp": 1451374817380, "from": "4c9343846613f66931000007", "to": "4cc8ad306899f56692000004", "label": "friend"}
   ]
   '
   

5. select index edges.

   curl -XPOST localhost:9000/graphs/getEdges -H 'Content-Type: Application/json' -d '
   {
       "srcVertices": [{
           "serviceName": "s2graph-test",
           "columnName": "user_id",
           "id": "4c9343846613f66931000007"
       }],
       "steps": [{
           "step": [{
               "label": "path_friend",
               "direction": "out",
               "offset": 0,
               "limit": 10
           }]
       }]
   }
   '
   

   this gives no edges which is expected.
   then with "_to" specified, then it gives deleted edge.

curl -XPOST localhost:9000/graphs/getEdges -H 'Content-Type: Application/json' -d '
{
    "srcVertices": [{
        "serviceName": "s2graph-test",
        "columnName": "user_id",
        "id": "4c9343846613f66931000007"
    }],
    "steps": [{
        "step": [{
            "label": "path_friend",
            "direction": "out",
            "offset": 0,
            "limit": 10, 
            "_to": "4cc8ad306899f56692000004"
        }]
    }]
}
'

I think after delete operation finished, there should be no edge left even with "_to" option.
