Ultipa Graph's Memory Index

Answer this question
Resolved
suchangqin2022-11-30

Is the idea of 'memory index' the only reason why Ultipa is fast? I mean if Neo4j, TigerGraph or other manufacturers also implement this technique, will they achieve similar query performance?

    Hi!

    Actually as one of the first graph database providers, Neo4j has already implemented memory index approach. However, Ultipa and Neo4j have different storage structures of underlying data; the complexity and execution efficiency of algorithms coded in different languages, such as Java and C++, can vary by 10 times or more. These all determine how much CPU you need to compute on graphs. Another fact is that Neo4j cannot take full use of the CPU resource when traversing against graphs. It only uses part of all CPU cores for parallel computing, while Ultipa squeezes the computing power out from all CPU cores.
