Edge id is different between gremlin console and vertex program

[Saloni Agarwal]

Hi, I'm using jansugraph with Cassandra + ES combination and doing data ingestion with OLAP mode using the vertex program.
Edge id which I'm getting from gremlin console is different from value coming from the vertex program.

Edge id from gremlin console - 

gremlin> g.E()

==>e[42bn5v-215tzs-ro5-2pjr34][122884120-Identity->163844320]

Edge id from vertex program - 

@Override

public void execute(final Vertex vertex, final Messenger<Object> messenger, final Memory memory) {

    Iterator<Edge> edgeIterator = vertex.edges(Direction.BOTH);

    while (edgeIterator.hasNext()) {

        Edge edge = edgeIterator.next();

        logger.info("edge_id = {}", edge.id().toString());

    }

}

edge_id = 245767171

How can I get the same values from both places?

Try this:

g.E().next().id().getRelationId()

Best wishes,

Marc

Thanks Marc !!

though I wanted to know, is there a way to get edge id rather than relationid from vertex program?

Without repeating your experiment I do not understand how the edge.id().toString() logging can result in a single number. Can you also log the edge.id().getClass() ?

I would expect the edge.id() to be an instance of:

https://github.com/JanusGraph/janusgraph/blob/v0.5.2/janusgraph-driver/src/main/java/org/janusgraph/graphdb/relations/RelationIdentifier.java

(as it is for OLTP g.E().next().id().getClass())
