Re: org.janusgraph.diskstorage.TemporaryBackendException: Wrote claim for id block

Ankur Goel <ankur...@...>
 

java code that i am using for data uploading:

{
int loopCounter = getTotalNoofRecorsdCountFromDB();
List<Data> data = getData fromDB();
JanusGraphTransaction tx = graph.newTransaction();
for (int i = 0; i < loopCounter; i++) {
                VerticesDTO vertex = data.get(i);
                Vertex v = tx.addVertex(T.label, "data", dataid, vertex.getDataId());
                v.property("vlabel", "taglead");
                v.property("prop1", vertex.getProp1());
                v.property("prop2", vertex.getProp2());
                v.property("prop3", vertex.getProp3());
                v.property("prop4", vertex.getProp4());
                v.property("prop5", vertex.getProp5());
                v.property("prop6", vertex.getProp6());
                v.property("prop7", vertex.getProp7());
                List<String> prop8 = getProp8();
                prop8.forEach(p -> v.property("prop8", p));
                List<String> prop9 = getProp9();
                prop9.forEach(p -> v.property("prop9", p));
                List<String> prop10 = getProp10();
                prop10.forEach(p -> v.property("prop10", p));
                
                
                if(i%1000 ==0){
                    tx.commit();
                }
            }
tx.commit();
}


Please suggest.
