摘    要:随着数据流应用系统的快速流行,流数据管理对数据库技术提出了巨大挑战。由于数据流经常是爆发性的且数据特征可能随时变化,因此要求数据流管理系统具有很好的自适应性。当输入速率超过系统处理能力时,系统会产生过载且性能下降。为了解决这一问题,卸载技术是有效的途径之一。卸载时间、卸载地点和卸载数量是与卸载技术密切相关的三个主要问题,本文主要从这三个方面来综述和分析目前各个数据流系统所采用的卸载技术。

关 键 词:数据流  卸载  自适应性  数据库技术  应用系统  综述  数据管理  数据特征  管理系统  处理能力

Abstract:With the rapid popular of data stream application systems, management of data streams is a huge challenge on database technology. Since data streams are often bursty and data characteristics may vary over time, it is required that data stream systems must have a good adaptability. When input rates exceed the system processing capacity, the system will become overloaded and the performance will deteriorate. To solve this problem, load shedding is one of promising approaches. When, where in the query network and how much load to shed are three main problems closely related to load shedding techniques. This paper surveys and analyzes from these three points load shedding techniques adopted in various existing data stream systems.
Keywords:Data streams  Load shedding  Adaptability
