Abstract

In various embodiments, a method for processing event streams includes receiving a finite state machine defined in response to a set of processing components, a set of states, and a set of entry points. Event data associated with an event stream is also received. The event data is processes according to the finite state machine to generate an event.

Claims

1. A method for processing event streams, the method comprising:

receiving a finite state machine defined in response to a set of processing components, a set of states, and a set of entry points;

receiving event data associated with an event stream; and

processing the event data according to the finite state machine to generate an event.

2. The method of claim 1 further comprising:

receiving the set of processing components, wherein each of the processing components comprises one or more operations.

3. The method of claim 2 wherein the one or more operations comprise at least one of a logical operation, an arithmetic operation, a binary operation, and a compare operation.

4. The method of claim 1 further comprising:

receiving the set of states, wherein each of states identifies one or more relationships between a first processing component and a second processing component.

5. The method of claim 1 further comprising:

receiving the set of entry points, wherein each entry point identifies one or more states as start states associated with the finite state machine.

6. The method of claim 1 further comprising:

generating the finite state machine based on the set of processing components, the set of states, and the set of entry points.

7. A system for processing event streams, the system comprising:

a processor; and

a memory coupled to the processor, the memory configured to store a plurality of code modules which when executed by the processor cause the processor to;

receive a finite state machine defined in response to a set of processing components, a set of states, and a set of entry points;

receive event data associated with an event stream; and

process the event data according to the finite state machine to generate an event.

8. The system of claim 7 wherein the processor is configured to:

receive the set of processing components, wherein each of the processing components comprises one or more operations.

9. The system of claim 8 wherein the one or more operations comprise at least one of a logical operation, an arithmetic operation, a binary operation, and a compare operation.

10. The system of claim 7 wherein the processor is configured to:

receive the set of states, wherein each of the states identifies one or more relationships between a first processing component and a second processing component.

11. The system of claim 7 wherein the processor is configured to:

receive the set of entry points, wherein each entry point identifies one or more states as start states associated with the finite state machine.

12. The system of claim 7 wherein the processor is configured to:

generate the finite state machine based on the set of processing components, the set of states, and the set of entry points.

13. A computer program product stored on a computer readable medium for processing event streams, the computer program product comprising:

code for receiving a finite state machine defined in response to a set of processing components, a set of states, and a set of entry points;

code for receiving event data associated with an event stream; and

code for processing the event data according to the finite state machine to generate an event.

14. The computer program product of claim 13 further comprising:

code for receiving the set of processing components, wherein each of the processing components comprises one or more operations.

15. The computer program product of claim 14 wherein the one or more operations comprise at least one of a logical operation, an arithmetic operation, a binary operation, and a compare operation.

16. The computer program product of claim 13 further comprising:

code for receiving the set of states, wherein each of the states identifies one or more relationships between a first processing component and a second processing component.

17. The computer program product of claim 13 further comprising:

code for receiving the set of entry points, wherein each entry point identifies one or more states as start states associated with the finite state machine.

18. The computer program product of claim 13 further comprising:

code for generating the finite state machine based on the set of processing components, the set of states, and the set of entry points.
