JanusGraph (janusgraph.org) is a leading open source graph database that offers a pluggable storage layer and Scylla is becoming the storage layer of choice. This talk will outline how JanusGraph leverages Scylla under the covers and then explore potential use cases that can be built once you have the ecosystem in place.

Why NoSQL for a Graph Backend?
Horizontal scalability - Distributed clusters for always-on availability
○ Better for massive data volumes (terabytes to petabytes)
○ Better for high velocity ingestion (even hundreds of millions of endpoints)
Flexible data modeling - even automatically-generated schema
○ Better for wide variety of data (from real-time sensor data to blobs)
Faster exploration of data - No JOINs minimizes data complexity
○ Graph model more efficient for querying than relational
○ Lower latencies
