    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: 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: Systems and methods are disclosed that determine a duration and resources for testing software. In some implementations, the system performs operations including determining functions performed by applications of the software product, and determining categories based on the functions, the categories including a lowest-criticality category and a highest-criticality category. The operations also include determining degrees of change to the applications and test scripts corresponding to the degrees of change. The operations also include generating a data structure based on the categories and the degrees of change, the data structure including columns identifying the categories in an order from lowest to highest criticality. The operations also include determining weights corresponding to distances of the categories from the highest-criticality category. The operations also include determining a set of test scripts based on the weights, the test scripts, and the degree of change indicators, and determining the resources based on the set of test scripts.

    摘要: Techniques for detecting patterns in one or more data or event streams. A pattern to be detected may be specified using a regular expression. Events received in a data stream are processed during runtime to detect occurrences of the specified pattern in the data stream. In one embodiment, a pattern type or class is determined for the specified pattern and pattern matching is performed using a technique selected based upon the type or class determined for the specified pattern.

    摘要: Techniques for detecting patterns in data streams. A pattern to be detected may be specified using a regular expression. Events received in data streams are then processed during runtime to detect occurrences of the pattern specified by the regular expression in the data stream. If the pattern to be matched belongs to a certain predetermined class of patterns, then a pattern matching technique that is customized for that class of patterns is used during the runtime events processing.
