Performance comparison of relational databases and columnar databases using bitmap index for fast search of 10gbps network flows

Recently a lot of Cyber Attacks are done. In order to prevent these Cyber Attacks, first we should be able to analyze attacks from network traffic like packets and flows. However, in high speed network like 10Gbps, there are millions of packets and tens of thousands of flows per second. So, it is very difficult just to find a flow which a security investigator wants to see within a short time. To make search fast, we have to use indexes used in databases. In this paper, we show loading time and search time in relational database and columnar database using bitmap index.
