Abstract: A method for joining an event stream with reference data includes loading a plurality of reference data snapshots from a reference data source into a cache. Punctuation events are supplied that indicate temporal validity for the plurality of reference data snapshots in the cache. A logical barrier is provided that restricts a flow of data events in the event stream to a cache lookup operation based on the punctuation events. The cache lookup operation is performed with respect to the data events in the event stream that are permitted to cross the logical barrier.

Abstract: Described herein is a system and method for dynamically scaling a stream processing system (e.g., “exactly once” data stream processing system). Various parameter(s) (e.g., user-configurable capacity, real-time load metrics, and/or performance counters) can be used to dynamically scale in and/or scale out the “exactly once” stream processing system without system restart. Delay introduced by this scaling operation can be minimized by utilizing a combination of mutable process topology (which can dynamically assign certain parts of the system to a new host machine) and controllable streaming processor movement with checkpoints and the streaming protocol controlled recovery which still enforces the “exactly once” delivery metric.
