摘要：Certain example embodiments relate to using Complex Event Processing (CEP)

techniques for statistical analysis of cache behavior and parameters, e.g., in connectionwith large, potentially heterogeneous data sets (e.g., “Big Data”). A dedicated streammining operator registers a listener to a cache and receives notifications on cacheoperations. For selected element attributes, a first model estimates the probabilitydensity functions of the attribute values, delivering well-defined estimates of theattribute value distributions. A second model analyzes the time elements stay in thecache (“validity”). Validity is combined with the attribute value distribution. Ameaningful analysis model (Cache Element Model) can be derived by combiningadditional summary statistics for the validity with the attribute value distribution,describing how long elements stay in the cache for attribute values of a specific region,and how the values are distributed. It may be used to inform administrative tasks such as,optimization of cache parameters.
