EVENT PROCESSING SYSTEM PAGING
First Claim
Patent Images
1. A system comprising:
- a processor coupled to a memory, the processor configured to execute the following computer-executable components stored in the memory;
a first component configured to receive an event-processing query; and
a second component configured to rewrite the event-processing query in a pageable form that supports swapping of at least a portion of the query into and out of the memory.

Abstract
A pageable query can be generated based on an event-processing query. The pageable query is a form of the event-processing query that supports swapping the event-processing query into and out of memory. For instance, page-in and page-out triggers can be inserted. After detection of a page-in trigger, the event-processing query can be loaded into the memory, and after detection of a page-out trigger, the event-processing query can be unloaded from memory.

7. A method comprising:
-
employing at least one processor configured to execute computer-executable instructions stored in a memory to perform the following acts; receiving an event-processing query; and generating a pageable query based on the event-processing query, wherein the pageable query supports swapping of at least a portion of the event-processing query into and out of the memory. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15)

16. A computer-readable storage medium having instructions stored thereon that enable at least one processor to perform a method upon execution of the instructions, the method comprising:
-
detecting a page-in trigger with respect to an event sequence; and loading at least a portion of an event-processing query into memory in response to detecting the page-in trigger. - View Dependent Claims (17, 18, 19, 20)
