    Abstract: A method may include receiving a continuous query identified by an archived relation associated with an application. The method may also include generating a physical query plan. Additionally, the method may include constructing a structured query language (SQL) equivalent expression corresponding to an attribute utilized by the operator and/or constructing an output SQL expression for the identified operator based at least in part on the SQL equivalent expression. Additionally, the method may include constructing the archiver query for the identified operator based at least in part on the output SQL expression. Further, the method may include executing the archiver query to obtain a result set of data records related to the application and/or generating a snapshot output of one or more data values related to the application based at least in part on the result set of data records.

    Abstract: A continuous query identified by an archived relation of an application may be received. A physical query plan may be generated for the continuous query and/or a child operator plan may be identified. A buffer operator may be inserted between the child operator and its parent operator and/or the event information from the child operator may be stored in the buffer operator. A query operator may be identified in the physical query plan. It may be determined that the query operator identified in the physical query plan is a same type as a second query operator in a second continuous query concurrently executing. Further, a combined query plan may be generated based at least in part on the query operator identified in the physical query plan being the same type as the second query operator in the second continuous query.

    Abstract translation: 可以接收通过应用的存档关系识别的连续查询。 可以为连续查询生成物理查询计划,和/或可识别子操作员计划。 可以在子操作符和其父操作符之间插入缓冲操作符和/或来自子操作符的事件信息可以存储在缓冲操作器中。 可以在物理查询计划中识别查询运算符。 可以确定在物理查询计划中识别的查询运算符与第二连续查询并发执行中的第二查询运算符相同。 此外,可以至少部分地基于在物理查​​询计划中识别的与第二连续查询中的第二查询运算符相同类型的查询运算符来生成组合查询计划。
