Hello, Let me share my recent works below: https://github.com/heterodb/pg-strom/wiki/804:-Pcap2Arrow
This standalone command-line tool allows to capture network packets from network interface devices, and convert them into Apache Arrow data format according to the pre-defined data schema for each supported protocol (TCP, UDP, ICMP x IPv4, IPv6), then write out the destination files. It internally uses PF_RING [*1] to support fast network interface card (> 10Gb), and to minimize packet losses by utilization of multi-core CPUs. Even though I confirmed that Pcap2Arrow write out the captured network packets more than 50Gb/s ratio, my test cases are artificial and biased traffic patterns. If you can test the software on your environment, it makes sense to improve the software. [*1] https://www.ntop.org/products/packet-capture/pf_ring/ As you may know, network traffic data tends to grow so large, thus, it is not easy to import them into database systems for analytics. Once we can convert them into Apache Arrow, we don't need to import the captured data again. Just map the files prior to analytics.
