- def produceOutputWatermark(inputWatermarkMs: Long): Option[Long]
Produce the output watermark for given input watermark (ms).
Produce the output watermark for given input watermark (ms).
In most cases, this is same as the criteria of state eviction, as most stateful operators produce the output from two different kinds:
1. without buffering 2. with buffering (state)
The state eviction happens when event time exceeds a "certain threshold of timestamp", which denotes a lower bound of event time values for output (output watermark).
The default implementation provides the input watermark as it is. Most built-in operators will evict based on min input watermark and ensure it will be minimum of the event time value for the output so far (including output from eviction). Operators which behave differently (e.g. different criteria on eviction) must override this method.
Note that the default behavior wil advance the watermark aggressively to simplify the logic, but it does not break the semantic of output watermark, which is following:
An operator guarantees that it will not emit record with an event timestamp lower than its output watermark.
For example, for 5 minutes time window aggregation, the advancement of watermark can happen "before" the window has been evicted and produced as output. Say, suppose there's an window in state: [0, 5) and input watermark = 3. Although there is no output for this operator, this operator will produce an output watermark as 3. It's still respecting the guarantee, as the operator will produce the window [0, 5) only when the output watermark is equal or greater than 5, and the downstream operator will process the input data, "and then" advance the watermark. Hence this window is considered as "non-late" record.
