Hi all

- The interaction with the underlying KV store via janusgraph client hits the `system_properties` table with a range query where the key is `configuration` (key = 0x636f6e66696775726174696f6e)

- The observation is that the janusgraph client stores all the configurations (static + dynamic) is stored against `configuration` key

- When we run the job with spark executors, where each executor is using janusgraph embedded mode, each of these executors create executor level entries (dynamic) with the same key `configuration`

- Thus as the number of executors increase, the particular partition with the key `configuration` starts becoming a large partition, and queries with key=`configuration` become range queries scanning the large partition as seen in below graphs (these are from scylla monitoring grafana dashboard)

- I would like to know if this there is a fix in progress for this issue - we at zeotap are using JanusGraph at tremendous scale (single graphs having 70 billion Vertices and 50 billion edges) and have identified couple of solutions to fix this
