1. A system comprising:
- a memory; and
a processor coupled to the memory, the processor configured to;
determine that a query includes a first function for whose evaluation an index is not natively provided by an event processing system that is to compile the query;
provide a data cartridge to the event processing system, the data cartridge providing an indexing scheme for evaluating the first function of the query; and
use, by the event processing system, the indexing scheme provided by the data cartridge to evaluate the first function of the query, wherein the processor is further configured to;
determine an occurrence of a link definition in the query, the link definition identifying the first function and the data cartridge;
determine a list of input arguments to the first function, wherein the list of input arguments comprises a collection;
determine whether the data cartridge provides an index for evaluation of the first function with the set of input arguments;
compile the query using information provided by the data cartridge to generate executable code, the executable code comprising an index instance generated using the information provided by the data cartridge, the index instance being generated for evaluation of the first function; and
execute the executable code, wherein the execution causes execution of the first function provided by the data cartridge related to the index instance.

Abstract
A framework or infrastructure (extensibility framework/infrastructure) for extending the indexing capabilities of an event processing system. The capabilities of an event processing system may be extended to support indexing schemes, including related data types and operations, which are not natively supported by the event processing system. The extensibility is enabled by one or more plug-in extension components called data cartridges.

9. A non-transitory computer-readable storage medium storing a plurality of instructions for controlling a computer system, the plurality of instructions comprising:
-
instructions that cause the computer system to determine that a query includes a first function for whose evaluation an index is not natively provided by an event processing system that is to compile the query; instructions that cause the computer system to provide a data cartridge to the event processing system, the data cartridge providing an indexing scheme for evaluating the first function of the query; and instructions that cause the computer system to use the indexing scheme provided by the data cartridge to evaluate the first function of the query, wherein the instructions further comprise; instructions that cause the computer system to determine an occurrence of a link definition in the query, the link definition identifying the first function and the data cartridge; instructions that cause the computer system to determine a list of input arguments to the first function, wherein the list of input arguments comprises a collection; instructions that cause the computer system to determine whether the data cartridge provides an index for evaluation of the first function with the set of input arguments; instructions that cause the computer system to compile the query using information provided by the data cartridge to generate executable code, the executable code comprising an index instance generated using the information provided by the data cartridge, the index instance being generated for evaluation of the first function; and instructions that cause the computer system to execute the executable code, wherein the execution causes execution of the first function provided by the data cartridge related to the index instance. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. A method comprising:
-
determining that a query includes a first function for whose evaluation an index is not natively provided by an event processing system that is to compile the query; providing a data cartridge to the event processing system, the data cartridge providing an indexing scheme for evaluating the first function of the query; and using, by the event processing system, the indexing scheme provided by the data cartridge to evaluate the first function of the query, using the indexing scheme provided by the data cartridge further comprising; determining an occurrence of a link definition in the query, the link definition identifying the first function and the data cartridge; determining a list of input arguments to the first function, wherein the list of input arguments comprises a collection; determining whether the data cartridge provides an index for evaluation of the first function with the set of input arguments; compiling, by a computer system, the query using information provided by the data cartridge to generate executable code, the executable code comprising an index instance generated using the information provided by the data cartridge, the index instance being generated for evaluation of the first function; and executing, by the computer system, the executable code, wherein the execution causes execution of the first function provided by the data cartridge related to the index instance. - View Dependent Claims (18)
