* VoltDB customers
“Event triggered, real-time
recommendations based on
customer behavior have 10-15
times the response rates than
mass marketing”
“We get competitive advantage
by analyzing device and user
data to create an interactive
and personalized consumer
experience across all devices.”
“Real time contextual offers
increase offer uptake rates by
75% and data revenues by
15%.”

TRADITIONAL RDBMS
•  Heavy Overhead
•  1000s of concurrent versions
•  Contention for locked records
•  Contention for latching on lock table
•  Index bottlenecks
•  Disk I/O bottlenecks
•  Architecture limits scaling

•  Is the fast layer streaming?
•  It is often more like fast OLTP
•  How do the pieces communicate?
•  OLAP analytics from Big -> Fast
•  New events from Fast -> Big
•  Where do “analytics” belong?
•  Analytics per-event: with Fast
•  Analytics across history: with Big
•  Are streaming frameworks equivalent?
•  Traditional SQL CEP (Esper, Streambase)
•  Tuple DAGs (Storm)
•  Window processors on Hadoop (Spark)

SOURCES OF STATE
1.  Analytics outputs must be query-able.
2.  “Lookup tables” to create groupings for analytics
and to supply enrichment data.
3.  Session managements: grouping, filtering and
aggregating create intermediate state.
