Some burgeoning web applications, such as web search engines, need to track, store and analyze massive real-time users' access logs with high availability of 24*7. The traditional high availability approaches towards general-purpose transaction applications are always not efficient enough to store these high-rate insertion-only archived streams. This paper presents an integrated approach to store these archived streams in a database cluster and recover it quickly. This approach is based on our simplified replication protocol and high performance data loading and query strategy. The experiments...
