The project, partially funded by an [http://cordis.europa.eu/mariecurie-actions/irg/home.html FP6 Marie Curie International Reintegration Grant], started in September 2007. Since then, we have developed benchmarking tools, carried out a number of performance evaluations on real CEP engines, and studied several use-cases of the technology. Currently, we are working towards the definition of novel application benchmarks that allow assessing the overall performance and scalability of event processing platforms. |
| - | + | The ''BiCEP benchmark suite'' shall comprise a number of smaller, domain-specific benchmarks, each with its own workload, dataset and metrics. Our goal is that each benchmark will allow evaluating one or more aspects of event processing systems (e.g. latency, scalability with respect to number of queries and rules, storage efficiency, etc.). | |
| + | <!-- | ||
| + | In the papers below we present benchmarking experiments that evaluate engines CEP along several metrics. Some of these are obvious, others not quite: throughput, maximum latency, latency degradation ratio, post-peak latency variation ratio, memory consumption, instruction count, clocks-per-instruction, cache miss rates and more. We studied many different basic and not so basic operations such as selection, projections, aggregations, joins, windows, and patterns detection and the impact of types and sizes of windows, query sharing, variations to peaks, the effects of garbage collection options, and internal data structures and tuple representations. | ||
| - | + | To perform all this, we built FINCoS, a testing framework (available below) that lets users generate and/or load test data, start and play benchmarking experiments, visualize and capture metrics, and run multiple engines at the same time. | |

* '''Sustainable throughput''': the steady-state number of events per unit of time that a (warmed-up) CEP engine can process while performing query processing. Even within the same system, sustainable throughput can vary widely depending on the amount of work to be done during query processing. | * '''Sustainable throughput''': the steady-state number of events per unit of time that a (warmed-up) CEP engine can process while performing query processing.
