Hi, Thanks for the reply. I use labels for different graph pattern matching algorithm e.g. Subgraph isomorphism, bi-simulation, ...... I use getLabels().iterator().next().name() but I don't use dataGraph.getAllLabels() or dataGraph.getAllLabelsInUse(). I can wait for getting the label from disk no need to be in memory(because I have my own neighborhood indexing which works just by demand on the part of the graph that I'm focusing on)
