NiagaraCQ: A Scalable Continuous Query System for Internet Databases

Summary: NiagaraCQ scales Internet-scale continuous queries by grouping common structures to share work and reduce I/O. It supports incremental re-grouping, a lightweight query-split approach, and uniform handling of change- and timer-based queries, with pull/push detection and caching for scalability.
