How can I get a list of indexed keys in Janusgraph?

Question

In Titan, I could get a list of indexed key using this stackoverflow post - https://stackoverflow.com/a/18497954/1647476. We switched to using Janusgraph 0.2.0. Does anyone know how can I get a list of indexed keys in Janusgraph?

Thank you.

In a Gremlin console

mgmt = graph.openManagement()
mgmt.getGraphIndexes(Vertex.class)

It will return a list of index names. If you want to know which field keys are associated to a particular index:

mgmt.getGraphIndex('my_index_name').getFieldKeys()
