I tried adding a composite index based on 2 existing properties.
As far as I understand, the initial stated is INSTALLED, then after all instances become aware of it, it should be REGISTERED.
Only then, I should re-index to make the index ENABLED.
My index remains INSTALLED. The JanusGraph server has no other instances (GKE deployment, with just 1 replica).
What needs to be done for the index to transition from INSTALLED to REGISTERED?
