The High-speed Filter can extract data from events received by input adapters (extraction process), and can join them to master data (join processing). After input events are processed by the high-speed filter, they are passed to the complex event processing.
Filter rules are the rules for describing the extraction process and the join processing. Input events can be in CSV format or XML format, and rules (the ON statement described later in this document) are described for each event type that indicates the structure of event data.
Filter rules are described in the rule definitions deployed to the CEP engine, and the syntax is checked when the CEP engine starts.
Point
Input events are passed to the complex event processing only if the setting for using complex event processing is set in the event type definition.
If filter rules are omitted from the rule definitions, input events are passed directly to the complex event processing.
Note
CEP engine startup fails if the syntax check detects an error.
