             Summary: Add a meta field(source_id, target_id) to GraphQL Edge Query (label)
                 Key: S2GRAPH-234
                 URL: https://issues.apache.org/jira/browse/S2GRAPH-234
             Project: S2Graph
          Issue Type: Improvement
          Components: s2graphql
            Reporter: Daewon Jeong


Add a meta field(source_id, target_id) to GraphQL Edge Query (label)

In Vertex Query(ServiceColumn) there is a fixed field called id.
 However, there is only a ServiceColumn for the connected source/target in the Edge (label).

Therefore, in order to access the Source/Target ServiceColumn id of an Edge at the time of GraphQL query, 
 it is necessary to access in the same format as the corresponding ServiceColumn { id }


This is logically very clear, but it is inconvenient in actual use.

For more convenient queries, add a meta field to the Edge such as _source, _target, and so on.


The `source_id` indicates the id value of the Source ServiceColumn.
 The `target_id` indicates the id value of the Target ServiceColumn.


If the above applies, you can query all of them in the following two ways.

 as is
{noformat}
{
  s2graph {
    User(id: "daewon") {
      id
      Like(limit: 10) {
        Book {
          id
        }
      }
    }
  }
}
{noformat}

to be
{noformat}
{
  s2graph {
    User(id: "daewon") {
      id
      Like(limit: 10) {      
        target_id
      }
    }
  }
}
{noformat}
