Re: Multiple indexes for the same property key with different label constraints

Robert Dale <rob...@...>
 

You can do that. I create each index in separate transactions.  I push the `awaitGraphIndexStatus` to a thread pool so subsequent indexes can be created. Then after all that, I loop through and ENABLE each index in one transaction. Also, I would consider using 0.2-SNAPSHOT from master as there has been some index related work there. But there's still a lot of work to be done for index management IMO.

I think the root of my problems is that I am trying to create two indexes on the same property key, but with different label constraints on the vertices.  This seemed like a very natural and useful thing to do.  Is it supported (for either composite or mixed indexes)?  I am using cassandra for storage and elasticsearch as my mixed index backend,

I'm trying to add a mixed index with one key to an existing graph.  After building the index, I do a commit on the JanusGraphManagement, and then awaitGraphIndexStatus(graph, mykey).call().  The resulting report says the index is REGISTERED, but if I look inside the report success=false and my key is in the "notConverged" collection, marked "INSTALLED".  Subsequent attempts to enable the index are not successful.  The key also shows up as INSTALLED if I look at what is returned from getGraphIndexes.  What does it mean for a key to be "notConverged", and what might I be doing wrong?  I've tried to follow the procedure in the documentation fairly carefully.
