Complex event processing (CEP) adapters for CEP systems for receiving objects from a source and outputing objects to a sink
First Claim
Patent Images
1. A computer system, comprising:
- a processor;
a memory coupled to the processor; and
a first interface configured to receive an event object from a source, wherein the first interface is further configured to receive the event object from the source via an input event object stream; and
a second interface configured to transmit a result object to a sink, wherein the second interface is further configured to transmit the result object to the sink via an output result object stream;
wherein the processor is configured to retrieve and execute instructions from the memory configured to;
insert the event object into an input queue when the input queue is not full;
stop receipt of event objects at the first interface when the input queue is full;
execute at least one declarative complex event processing (CEP) query with respect to the event object to generate the result object;
insert the result object into an output queue; and
remove the result object from the output queue and transmit the result object to the sink via the second interface.

Abstract
Methods, systems, and computer-readable media are disclosed for implementing adapters for event processing systems. A particular system includes an input adapter configured to store event objects received from a source at an input queue. The system also includes a query engine configured to remove event objects from the input queue, to perform a query with respect to the removed event objects to generate result objects, and to insert result objects into an output queue. The system also includes an output adapter configured to remove result objects from the output queue and to transmit the result objects to a sink.
