SASE Home

Update: our latest paper "On Complexity and Optimization of Expensive Queries in Complex Event Processing" is accepted by SIGMOD 2014. (more...)

We are delighted to release the first version of SASE - SASE 1.0. (more...)

Today high-volume event streams naturally exist in a variety of environments including sensing devices, financial services, network monitors, etc. An increasing number of applications require that useful information be extracted from such event streams in a timely manner. Such translation from event streams to useful, actionable information is realized by a new processing paradigm called complex event processing. CEP aims to provide a set of core functions:

 
  • Filtering removes unwanted events
  • Correlation detects complex patterns across different events.
  • Aggregation computes aggregate values.
  • Transformation generates new types of events.
 

To this end, we are designing and implementing a complex event processor, which we call SASE (Stream-based And Shared Event processing). SASE provides:

 
  • A rich declarative event language
  • Formal semantics of the event language
  • Theorectical underpinnings of CEP
  • An efficient automata-based implementation
