Hi Anatoly,

"id" is the internal key used by janusgraph to represent vertex id.
So I would suggest you to add a different key for your use case and build index on it it will work for sure .

Hope this helps :) .

Abhay

 The index was created with these commands:

gremlin> vid = mgmt.getPropertyKey('id')
==>id
gremlin> mgmt.buildIndex('byId', Vertex.class).addKey(vid).buildCompositeIndex()

gremlin> mgmt.commit()

One sets label constraint with indexOnly, right? I didn't use it.

Hi,

How was your index defined?  You've shown that it exists and is enabled but not the creation.  Specifically, did you create it with a label constraint?   If so, your traversal is not including the label and that would be why it isn't used.

Hello

I have made an index for vertex property "id", the index is enabled, but still it is not used for the query according to the profiler. Please, give me advice on how to make index work.

gremlin> vindex = mgmt.getGraphIndex("byId")
gremlin> vindex.fieldKeys
==>id

mgmt.awaitGraphIndexStatus(graph, vindex.name()).status(SchemaStatus.ENABLED).call()
==>GraphIndexStatusReport[success=true, indexName='byId', targetStatus=[ENABLED], notConverged={}, converged={id=ENABLED}, elapsed=PT0.001S]

gremlin> g.V().has('id', '-9032656531829342390').profile()
