Overview Apache Flink Stateful Functions

WebFor fault-tolerant state, the ProcessFunction gives access to Flink’s keyed state, accessible via the RuntimeContext, similar to the way other stateful functions can access keyed state. The timers allow applications to react to changes in processing time and in event time. WebMetrics # Flink exposes a metric system that allows gathering and exposing metrics to external systems. Registering metrics # You can access the metric system from any user function that extends RichFunction by calling getRuntimeContext().getMetricGroup(). This method returns a MetricGroup object on which you can create and register new metrics. … the periodicity assumption states that:WebOct 13, 2024 · The StateFun runtime is built on-top of Apache Flink, and applies the same battle-tested technique that Flink uses as the basis for strongly consistent stateful … siccem sedu
