  • HANDLING FAULTS IN A CONTINUOUS EVENT PROCESSING (CEP) SYSTEM
    Publication number: 20140237289
    Abstract: The concept of faults and fault handling are added to the execution of continuous event processing (CEP) queries. By introducing fault handling techniques to the processing of CEP queries, users are enabled to instruct a CEP query processor to respond to faults in a customized manner that does not necessarily involve the halting of the CEP query relative to which the faults occurred. For example, a fault might be due to a temporary problem. Under such circumstances, the CEP query processor can be instructed to ignore the fault and allow the execution of the CEP query to continue relative to the remainder of the event stream. Alternatively, if the fault is due to a problem with the CEP query itself, then the CEP query processor can be instructed to propagate the fault through the query processing system until the fault ultimately causes the problematic CEP query to be halted.

  • VARIABLE DURATION NON-EVENT PATTERN MATCHING
    Publication number: 20140201225
    Abstract: Techniques for performing non-event pattern matching on continuous event streams using variable duration. The duration value used in non-event pattern matching can be variable. Accordingly, a first pattern match candidate can have a different associated duration from a second pattern match candidate for matches arising from events received via an event stream. In certain embodiments, the duration for a candidate pattern match may be based upon one or more attributes of an event that started the candidate pattern match or based upon an expression (e.g., an arithmetic expression) involving one or more attributes of the event.

  • VARIABLE DURATION WINDOWS ON CONTINUOUS DATA STREAMS
    Publication number: 20140201355
    Abstract: Improved techniques are provided for processing streams of data. The duration of the time that an event is eligible for remaining in a time-based window can be variable for different events received via the same event stream. In certain embodiments, the duration of time that an input event spends in a time-based window is a function of one or more values of one or more attributes of the event. Since different events can have different one or more attribute values, the different events can spend different amounts of time in the time-based window for that event stream. The amount of time that an event spends in a time-based window can be controlled via the one or more attributes of the event.

  • SUPPORT FOR A PARAMETERIZED QUERY/VIEW IN COMPLEX EVENT PROCESSING
    Publication number: 20140136514
    Abstract: The present invention includes a method for providing parameterized queries in complex event processing (CEP). The method includes providing a query template which includes one or more bind variables, providing sets of parameters corresponding to the one or more bind variables, and parsing the query template to determine positions of the one or more bind variables. The method further includes scanning the provided sets of parameters to determine which of the sets of parameters are to be bound to the one or more bind variables, binding the one or more bind variables which are determined to be bound to the sets of parameters, and substituting the bound one or more bind variables with the corresponding sets of parameters. The method further includes injecting all incarnations of the parameterized queries into the system, and one template/parameterized query is configured to run them all.

  • OPERATOR SHARING FOR CONTINUOUS QUERIES OVER ARCHIVED RELATIONS
    Publication number: 20140095447
    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.

It may be identified if the state of the operator identifies an event that detects a change to the dimension relation. The continuous query may be re-started based at least in part on the event that detects the change to the dimension relation.
