Running A Realtime Stats Service On My Sql
This document summarizes Kazuho Oku's presentation on running a real-time stats service on MySQL. Some key points: 1) Oku described Pathtraq, a web ranking service in Japan that collects over 1 million access records per day from 10,000 users. 2) To provide real-time analysis of this data, compressed tables are stored in RAM to avoid slow random access on HDD. Custom compression algorithms were developed to compress URLs and access stats. 3) Additional optimizations included creating a message queue, limiting pre-computation loads, and developing an in-memory cache system with locking to minimize database queries.
