Dave Maier -- Benchmark Brainstroming

Discussion
• An interesting property for a DSMS is overhead for fault tolerance (e.g. recovery time), since these systems are 24X7
• Has burstiness and variability been added to NEXMark? Answer: yes
• Isn't talk of developing benchmarks premature, since we do not have a concensus on the interesting applications yet?
  Two responses: (1) Get it done early to get early feedback
  (2) At the last Stream meeting, an early draft of NEXMark generated a very lively discussion

Jennifer Widom's clarification of the exploits
• Time Series means using various kinds of windows
• Complex scenarios require developers to use multiple applications, which means more context switching
• ACID means we can take advantage of QoS - specifically, load shedding

Domains that might hit our exploits:
• Medical Monitoring
• Traffic Management, incl. personalized output
• Fraud Detection
• US Squirrels Corp
• FinTime
• Network Management
• Online Auction

Discussion
• FinTime may be a good app to look into. It measures financial time series data
  response: Oracle has time-series extensions, and they are going into DB2, so we lose one of our exploits
• I really want sharing as an exploit
• Can we legally compare ourselves to Oracle?
  response: We can compare to SleepyCat publicly, then also say we compared similarly to other products
• We will need the assistance of a domain expert in defining each of these domains
• What about click-stream analysis?
  response: There are already many specialty apps available that we won't be able to beat
• What about air-traffic control domain?
  response: we'll need a domain expert to help us see if that addresses the exploits (Maybe Dave Gifford?)
• We won't be able to use a live stream benchmark. We'll want traces or simulations

Action items
• Define and implement a benchmark in three months
• Volunteers by next Friday (1/17)
• Shasha will check on the finance domain
• Must get more information on the domains we do not understand
