摘要： Techniques for logging data pertaining to the operation of a data stream processing server. In one set of embodiments, logging configuration information can be received specifying a functional area of a data stream processing server to be logged. Based on the logging configuration information, logging can be dynamically enabled for objects associated with the functional area that are instantiated by the data stream processing server, and logging can be dynamically disabled for objects associated with the functional area that are discarded (or no longer used) by the data stream processing server. In another set of embodiments, a tool can be provided for visualizing the data logged by the data stream processing server.

摘要： Facilitating flexible windows in querying continuous data streams. In one embodiment, a software code is associated with a window, wherein execution of the software code determines the values to be included in the window. On receiving a query indicating the window, the result of the query is generated based on the values in the window determined by execution of the software code. The software code may be identified by an identifier and thus used for different queries on the same or different continuous data streams.

摘要： Simplifying a user's task in specifying a family of logics, with each logic designed to potentially select different subsets of values from the same continuous data stream at the same time instant. In one embodiment, all the logics are together specified by a common user specified software code design to accept a set of parameters, with different logics resulting from execution of the software code with different parametric values. Thus, when closely related family of logics are to be developed, the common software code may be formulated, with the code being designed to accept parameters and providing different logics for different sets of parametric values corresponding to the parameters.

摘要： A method to create a partition by time/tuple based window in an event processing service is provided. When continuous data streams are received, tuples are stored in a data structure with partitions based upon partition keys. Only a specified amount of tuples may be stored in each partition. When a partition exceeds the specified number of tuples, the oldest tuples are removed from the data structure. Tuples stored beyond a specified time period are also removed from the data structure. Two data structures may also be used to implement a time/tuple based window. Tuples are stored in both a data structure with a partition by window and a data structure with a range window. Tuples are removed in the partition by window when tuples exceed the amount in the partition. Tuples are removed in the range window when tuples exceed a specified time period. The two data structures are synchronized.
摘要翻译：提供了一种在事件处理服务中通过基于时间/元组的窗口创建分区的方法。当连续数据流被接收时，元组被存储在具有基于分区键的分区的数据结构中。每个分区中只能存储一定量的元组。当分区超过指定数量的元组时，最旧的元组将从数据结构中删除。存储超过指定时间段的元组也从数据结构中删除。也可以使用两个数据结构来实现基于时间/元组的窗口。元组被存储在具有分区的数据结构的窗口和具有范围窗口的数据结构中。当元组超过分区中的数量时，元组在窗口中被删除。当元组超过指定的时间段时，元组在范围窗口中被移除。两个数据结构是同步的。

摘要： Techniques for managing memory usage of a processing system by spilling data from a memory to a persistent store based upon an evict policy are provided. A triggering event is detected. In response to the triggering event and based on the evict policy, it is determined whether data from the memory of the processing system is to be spilled to the persistent storage. The determination is made by comparing a level of free memory of the processing system with a threshold specified by the evict policy. The data is evicted from the memory.

摘要： Techniques for reducing the memory used for processing events received in a data stream are provided. This may be achieved by reducing the memory required for storing tuples. A method for processing a data stream includes receiving a tuple and determining a tuple specification that defines a layout of the tuple. The layout identifies one or more data types that are included in the tuple. A tuple class corresponding to the tuple specification may be determined. A tuple object based on the tuple class is instantiated, and during runtime of the processing system. The tuple object is stored in a memory.
