Reading Questions, Lecture 20 (11/22)
Aurora is a "stream management system" for processing continuous queries over "streams" -- sequences of stock quotes, traces of network
traffic, or runs of sensor data.
As you read the papers, consider the following questions:
- What features does Aurora offer that NiagaraCQ and eddies did not? What features does it lack?
- Do you think the Aurora idea of writing queries via "boxes and arrows" is a good one? How does Aurora deal with the desire to
share processing of multiple queries as in NiagaraCQ?
- What language constructs does Aurora introduce that are not in the relational model? How are those new language feature specially
tailored to work with data streams?
