The In-memory analytics server (PGX, or Property Graph AnalytiX) has an optimized representation of a property graph that uses less memory. Larger graphs can be analyzed in the same amount of memory.
Graph sizes are continuously growing larger. With this optimization you can analyze larger graphs using less memory than previously required. This not only enables analysis of more data, but also reduces system costs. The optimized graph representation gives you faster performance and is transparent; existing applications will run faster with no change.
