How to do indexing in Janusgraph Or Gremlin

First step :remote connect tinkerpop.server conf/remote.yaml session

Second Step :remote config timeout none

Third Step :remote console

Fourth Step graph.getOpenTransactions().size();

Fifth Step for(i=0;i<size;i++) {graph.getOpenTransactions().getAt(0).rollback()}

Note:- Replace size with output of fourth step

Sixth Step mgmt = graph.openManagement()

Seventh Step name = mgmt.getPropertyKey(‘name’)

Eighth Step bynameindex=mgmt.buildIndex(‘byNameComposite’, Vertex.class).addKey(name).buildCompositeIndex()

Ninth Step mgmt.commit();

Tenth Step ManagementSystem.awaitGraphIndexStatus(graph, “byNameComposite”).call();

Eleventh Step mgmt = graph.openManagement()

Twelfth Step mgmt.updateIndex(mgmt.getGraphIndex(“byNameComposite”), SchemaAction.REGISTER_INDEX).get();

Thirteenth Step mgmt.commit()

Fourteenth Step mgmt = graph.openManagement()

Fifteenth Step mgmt.updateIndex(mgmt.getGraphIndex(“byNameComposite”), SchemaAction.REINDEX).get()

Sixteenth Step mgmt.commit()

Seventeenth Step prop = mgmt.getPropertyKey(‘name’);

Eighteenth Step idx = mgmt.getGraphIndex(‘byNameComposite’);

Nineteenth Step status = idx.getIndexStatus(prop);

Twentieth Step print(status)

Hurray, You have enabled the property for indexing.

Now, Use it as follows.

g=graph.traversal()

g.V().property(‘name’,’Sumit’)

Now, you will get the result, before you can even blink your eyes, Even if you have billions of nodes.
