Re: ID block allocation exception while creating edge

Sharing detail on how i am creating node/edges to make sure nothing wrong with that which is resulting in ID allocation failures.

 

I am creating one static instance JanusGraph object on each spark worker box and using that i am creating multiple transaction and commit.

pairRDD.foreachPartition(partIterator -> {
partIterator.forEachRemaining( tuple -> {
createNodeAndEdge(tuple, JanusGraphConfig.getJanusGraph(janusConfig));
});
}); where JanusGraphConfig.getJanusGraph returns static instance.

 

In createNodeAndEdge() method i am creating GraphTraversalSource using static janusGraph, creating node, edge, committing and then closing GraphTraversalSource object, as shown below in pseudo code:

createNodeAndEdge(Tuple2<K, V> pair, JanusGraph janusGraph)

{

GraphTraversalSource g = janusGraph.buildTransaction().start().traversal();
 try{

      create node;

      create edge;
     
      g.tx().commit();

    }  catch ( Exception) {

     g.tx().rollback();
  } finally() {
    g.tx().close();

    g.close();
  }

}

 

Thanks,
Anjani
