1. A computer-readable memory storing a plurality of instructions for causing a processor to perform operations, the plurality of instructions comprising: instructions that cause the processor to detect a first fault raised by an operator of a first continuous execution processing (CEP) query relative to a first event from an event stream; instructions that cause the processor to invoke, in response to detecting the first fault, a first user-registered fault handler that has been registered with a CEP query processor; instructions that cause the processor to determine that the first user-registered fault handler caught and handled the first fault; and instructions that cause the processor to cause the CEP query processor, in response to determining that the first user-registered fault handler caught and handled the first fault, to continue to execute the first CEP query without halting execution of the first CEP query.
