摘要： Described herein are technologies pertaining to migrating state information of operators in a first continuous query plan to a second continuous query plan in an asynchronous manner, such that the first continuous query plan need not cease executing during the migrating of the state information. State information pertaining to stateful operators, such as join operators, is migrated from the first continuous query plan to the second continuous query plan by way of a transformation plan. State matching is utilized to generate the transformation plan.
摘要翻译：这里描述的是涉及将第一连续查询计划中的运营商的状态信息以异步方式迁移到第二连续查询计划的技术，使得在迁移状态信息期间第一连续查询计划不需要停止执行。通过转换方案，将有状态运算符（例如加入运算符）的状态信息从第一个连续查询计划迁移到第二个连续查询计划。利用状态匹配来生成转换计划。

摘要： Aspects of the subject matter described herein relate to stream operators. In aspects, a stream event is received. Based on a timestamp associated with the stream event and the number of stream operators that have asked to be activated prior to or at the timestamp, zero or more stream objects are informed of one or more time events and torn down if no longer needed. In addition, a destination stream operator is instantiated, if needed, data (e.g., the timestamp and packet, if any) corresponding to the stream event is provided to a stream operator, output data, if any, is received from the stream operator, and the stream operator is torn down if it no longer needs state data between invocations.

摘要： A query translation system and method for processing a streaming language query on existing or stored data. The streaming language query is applied against a data stream log by first translating the streaming language query into a database management system query (such as a SQL query) and then applying the translated streaming language query against the data stream log. Embodiments of the query translation system and method include a bitemporal converter that converts a bitemporal data stream log into a canonical history table format. Once in this format, embodiments of the query translation system and method translate a streaming language query into a SQL query. A categorization of each of the streaming operators that make up the streaming language query is performed to determine which translation technique to use. In general, one of three general translation techniques is used based on these categorizations of the streaming operators.

摘要： Described is a server monitoring technology that is scalable to large numbers of servers, e.g., in a datacenter. Agents on servers run queries to monitor data sources for that server, such as performance counters and other events. The agents monitor their resource usage and those of monitored events to stay within an administrator-specified resource budget (policy), e.g., by modifying the running queries and/or monitoring parameters. A controller receives results of the monitoring, analyzes the results, and takes action as needed with respect to server operation and monitoring. The controller may dynamically update an agent's queries, monitoring parameters and/or monitored data post-processing operations. The controller may issue alerts and reports, including alerts indicative of inter-server problems between two or more servers.

摘要： Currency and consistency requirements are specified as part of a query against a database that may contain replicated data that is updated asynchronously and therefore may not be completely up to date. The database system constructs query execution plans that include an input selection operator that verifies the currency of a replica and selects a subplan using the replica for execution only when the replica meets the query's currency constraints. It checks possible query execution plans at construction time against the query's consistency constraints and any plans that may produce a result not meeting the consistency constraints are rejected. In this way, the query result is guaranteed to satisfy the query's currency and consistency requirements.
摘要翻译：货币和一致性要求被指定为针对数据库的查询的一部分，数据库可能包含异步更新的复制数据，因此可能不完全是最新的。数据库系统构建查询执行计划，其中包括验证副本的货币的输入选择运算符，并且只有当副本符合查询的货币约束时才使用副本才能执行子计划。它可以根据查询的一致性约束在施工时检查可能的查询执行计划，并且拒绝可能产生不符合一致性约束的结果的任何计划。以这种方式，查询结果保证满足查询的货币和一致性要求。
