Fast Data Streaming App

The Fast Data Streaming app simulates real-time click stream processing. Click events are ingested into VoltDB at a high rate, then cleaned up and persisted into a data warehouse for historical analysis. Segmentation information is calculated in the data warehouse and stored back into VoltDB. VoltDB uses the information to segment real-time events for per-event decisioning.
