Abstract[English]
Provided in the embodiments of the present disclosure are a filter construction method and apparatus, and a device. The method comprises: for a data query plan, acquiring filter construction information corresponding to an operator chain corresponding to the data query plan, in order to determine join keys on which filters can be constructed; and then separately calculating the performance gain and/or the performance overhead brought by each filter; and determining, on the basis of the performance gain and/or the performance overhead, whether to construct a filter on a corresponding join key. In the embodiments of the present disclosure, the performance gain and the performance overhead brought by constructing filters can be fully taken into consideration, so as to selectively construct filters, thereby avoiding the overhead of constructed filters affecting the system performance.[French]
Les modes de réalisation de la présente divulgation concernent un procédé et un appareil de construction de filre, ainsi qu'un dispositif. Le procédé consiste : pour un plan d'interrogation de données, à acquérir des informations de construction de filtre correspondant à une chaîne d'opérateurs correspondant au plan d'interrogation de données, afin de déterminer des clés de jointure sur lesquelles des filtres peuvent être construits ; puis à calculer séparément le gain de performance et/ou le surdébit de performance apporté(s) par chaque filtre ; et à déterminer, en fonction du gain de performance et/ou du surdébit de performance, s'il faut construire un filtre sur une clé de jointure correspondante. Dans les modes de réalisation de la présente divulgation, le gain de performance et le surdébit de performance apportés par la construction de filtres peuvent être entièrement pris en considération, de sorte à construire sélectivement des filtres, ce qui évite le surdébit de filtres construits affectant les performances du système.[Chinese]
本公开实施例提供一种过滤器构建方法、装置及设备，对于数据查询计划，获取该数据查询计划对应的算子链对应的过滤器构建信息，以确定可以构建过滤器的连接键，再分别计算每个过滤器所带来的性能收益和/或性能开销，基于性能收益和/或性能开销来确定是否在对应的连接键中构建过滤器。在本公开实施例中，能够充分考虑构建过滤器所带来的性能收益和性能开销，从而选择性的构建过滤器，能够避免构建的过滤器的开销影响系统性能。
