流水线相关树查询优化器和调度器

本发明实施例提供了一种方法，包括：遍历具有多个节点的查询计划树，每个节点表示对查询的主题数据进行的操作，从而从查询计划树中提取多个流水线，识别所述提取的多个流水线之间的相关性，并根据所述提取的多个流水线之间的相关性来提供流水线相关树，以便由多个处理器进行查询。 A method includes traversing a query plan tree having multiple nodes, each node representative of an operation on data that is the subject of a query, to extract multipl...

Summary:本发明实施例提供了一种方法，包括：遍历具有多个节点的查询计划树，每个节点表示对查询的主题数据进行的操作，从而从查询计划树中提取多个流水线，识别所述提取的多个流水线之间的相关性，并根据所述提取的多个流水线之间的相关性来提供流水线相关树，以便由多个处理器进行查询。 A method includes traversing a query plan tree having multiple nodes, each node representative of an operation on data that is the subject of a query, to extract multiple pipelines from the query plan tree, identify dependencies between the multiple extracted pipelines, and provide a pipeline dependent tree based on the dependencies between the multiple extracted pipelines for execution of the query by multiple processors.
