AI Technical Summary
Technical Problem
Apache Flink can only count events that flow in continuously according to a fixed time sequence, which has poor applicability.
Method used
By defining event patterns and counting thresholds, target event matching logic is generated, enabling the counting of events that flow in continuously or discontinuously according to the target time sequence. Nondeterministic loosely continuous repeating count analysis is performed using the Repeat Until template and the Flink CEP dedicated library.
Benefits of technology
It enriches the counting semantics of complex event correlation analysis in Apache Flink, improves its applicability, enables the handling of non-continuous event inflows, and enhances compatibility and resilience in business scenarios.

Abstract
Embodiments of the present application disclose an event processing method, which comprises: determining an event pattern and a count threshold for pattern matching of an event stream; determining target counting logic for counting a number of target events matching the event pattern; wherein the target events at least comprise events flowing in discontinuously in a target time sequence; determining target event matching logic based on the event pattern, the count threshold and the target counting logic; wherein the target event matching logic is used to determine a composite event matching the event pattern and satisfying the count threshold; and processing the event stream to be processed based on the target event matching logic. Embodiments of the present application also disclose an event processing device, equipment and a computer readable storage medium.
