[ FLINK-3464] Use Processing-Time Clock in Window Assigners/Triggers Introduces a custom TimeServiceProvider to the StreamTask. This is responsible for defining and updating the current processingtime for a task and handling all related action, such as registering timers for actions to be executed in the future. [ FLINK-3669] Timer coalescing across keys and cleanup of unused trigg… …er tasks Per timestamp only one TriggerTask is registered at the runtime context. When the first timer is registered a new TriggerTask is sheduled. When no timer is registered anymore for a specific timestamp the corresponding trigger task is canceled and hence removed. 1.

Flink registertimer

KeyedProcessFunction is a user-oriented low level api provided by flink, which can access the state, the current water mark or the current processingtime. More importantly, it provides the function of registering timers, which can be divided into: The processElement () method registers timers for 24 hours after a shift started to clean up state that is no longer needed. Cleaning up the state is the only logic that the onTimer () method You need to use the underlying API process function provided by Flink. Process function can not only access timestamps and watermarks, but also register timer s triggered at a specific time in the future.

This method puts the service into a state where it does not register new timers, but returns for each call to registerTimer(long, org.apache.flink.streaming.runtime.tasks.ProcessingTimeCallback) or scheduleAtFixedRate(org.apache.flink.streaming.runtime.tasks.ProcessingTimeCallback, long, long) a "mock" future and the "mock" future will be never completed.

The timer service is This method puts the service into a state where it does not register new timers, but returns for each call to registerTimer (long, org.apache.flink.streaming.runtime.tasks.ProcessingTimeCallback) or scheduleAtFixedRate (org.apache.flink.streaming.runtime.tasks.ProcessingTimeCallback, long, long) a "mock" future and the "mock" future will be never completed. Registers a timer to be fired when the event time watermark passes the given time. Timers can internally be scoped to keys and/or windows. When you set a timer in a keyed context, such as in an operation on KeyedStream then that context will also be active when you receive the timer notification.

You may have to ask, how do I access timestamps and watermarks?
