    摘要: In one embodiment, a system for distributed event processing includes a first event processor and a second event processor. The first event processor receives event data associated with an event stream. The second event processor receives a query associated with the event stream. A request to the first event processor is generated by the second event processor based on the query for a first portion of event data associated with the event stream. The second event processor receives the first portion of event data from the first event processor. The second event processor then generates an event based on the first portion of event data.

    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: 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.
