INTRODUCTION
• What is CEP?
• Why Siddhi? • Our project
• What have we done?
• What are yet to come?
WHAT IS CEP ?
WHAT IS CEP
In abstract, the tasks of the CEP is to identify
meaningful patterns, relationships and data
abstractions among unrelated events and fire an
immediate response such as an Alert message.
WHY SIDDHI?
WHY SIDDHI?
• Current CEP solutions and their Cons
• Project objectives
• Improvements from Research
CURRENT CEP SOLUTIONS
• S4 • STREAM• Esper• SASE• Cayuga• TelegraphCQ• HiFi• Aurora• CompAS.• Niagara
WHAT ARE THE PROBLEMS WITH THEM?
• Proprietary
• Not enough support for complex queries
• Less efficient
High latency and High memory consumption
PROJECT OBJECTIVES
Primary Objective
• Carrying out research to come up with effective algorithms approaches to implement A High Performing CEP engine.
• Coming up with an effective architecture for a CEP Engine which can detect events in a computationallyefficient way.
PROJECT OBJECTIVES CONT'D...
Secondary Objective
• Finding out a query language that will be sufficient to express the full set of pattern queries.
• Provide additional features, such as out of order arrival of events.(Optional)
For State Machine
SASE: High-Performance Complex Event Processing over Streams
For Pipeline Architecture
Aurora: a new model and architecture for data stream management
For Query Plan Management
