(most of this description comes from an offline discussion between me, Arvid Heise, Roman Khachatryan, Aljoscha Krettek and Haibo Sun) In case of end of input (for example for bounded sources), all pending (untriggered) processing time timers are ignored/dropped.

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. This method puts the service into a state where it does not register new timers, but returns for each call to ProcessingTimeService.registerTimer(long, org.apache.flink.streaming.runtime.tasks.ProcessingTimeCallback) or ProcessingTimeService.scheduleAtFixedRate(org.apache.flink.streaming.runtime.tasks.ProcessingTimeCallback, long, long) a "mock" future and the "mock" future will be never After calling quiesce(), further calls to registerTimer(long, ProcessingTimeCallback) will not register any further timers, and will return a "dummy" future as a result. This is used for clean shutdown, where currently firing timers are waited for and no future timers can be scheduled, without causing hard exceptions.

Under alkoholrus dödade han sju personer och skadade tre i Falun under natten mot lördagen den 11 juni 1994. Flink dömdes i februari 1995 till livstids fängelse för morden. In the output from the snipped where the regular Apache Flink API for registering timers is used, two were registered at 10 (one from instance with timestamp 3 and one from instance with timestamp So, that inside of registerTimer function You may remove the previous timer. The other option can be to simply ignore that, but You need to take into account that multiple timers may fire consecutively and state may be actually null.

Shuts down and clean up the timer service provider hard and immediately. This does not wait for any timer to complete. Any further call to ProcessingTimeService.registerTimer(long, ProcessingTimeCallback) will result in a hard exception. The Flink’s context keeps the information of the current partition key, current timestamp (this unique id is generated and returned when the registerTimer function is called).
