    • Embodiments relate to re-writing database query plans, and visualizing such re-written query plans. A query re-write framework includes a query normalization engine in communication with a rule catalog comprising query re-write rules in the form of rule classes. The framework receives as input, a query plan graph to be re-written. Based upon the engine's application of re-write rules from the catalog, the framework produces a re-written query plan graph as output. An interface component of the framework may provide a visualization of the re-written query plan graph as part of a dashboard. A user may access the framework to enable/disable existing rules in the catalog, add new rules to the catalog, and/or control a sequence and a precedence in which rules are applied to re-write the query plan. A user may interact with the visualization of the re-written query plan for purposes of de-bugging, re-write optimization, and/or query development.
    • 实施例涉及重写数据库查询计划,以及可视化这种重写的查询计划。 查询重写框架包括与规则目录通信的查询规范化引擎,其包括规则类形式的查询重写规则。 该框架作为输入接收要重新写入的查询计划图。 基于引擎从目录中重写规则的应用程序,该框架生成重写的查询计划图作为输出。 框架的界面组件可以提供重写的查询计划图的可视化,作为仪表板的一部分。 用户可以访问框架以启用/禁用目录中的现有规则,向目录添加新规则,和/或控制应用规则重写查询计划的序列和优先级。 用户可以与重新编写的查询计划的可视化进行交互,以便进行解码,重写优化和/或查询开发。
