I have to drop thousands of vertex ids from the graph, and .drop().iterate() takes like 1 minute for each vertex. Seems like it is gonna take ages for my task to complete. Is there any other quicker way to achieve this? like a bulk drop operation?

Different vertex Ids with exactly same properties

I am using Janusgraph 1.0.0-rc2 with Cassandra as a backend. I recently encountered an issue where I saw two different vertices with different vertex ID but have exactly same properties, Even when I have indexed the property as UNIQUE. Is this a known issue of rc2 version?

StaleIndexRecordUtil.forceRemoveVertexFromGraphIndex not working

The job is getting successful, but I can still see the vertices in the graph. It is weird that even If I pass a non existent vertex ID, the job does not fail. any idea why such behavior? or am I missing something?

Should not allow creating vertex with only one of the composite index

I have created unique composite index using : .addKey(key1).addKey(key2).unique().buildCompositeIndex() I want to keep the combination of key1 and key2 unique. Please let me know if I can achieve that with the above statement. Also i found that janusgraph is allowing me to create vertices using only one of the key, for example i can create vertices with key1 only, why it is allowing me to do so? shouldnt it fail since key2 is not given?
