Apache Flink: Count window with timeout

Question

Here is a simple code example to illustrate my question:

case class Record( key: String, value: Int )

object Job extends App
{
  val env = StreamExecutionEn         


        

Answer 1

You could also do this with a custom window Trigger that fires either when the count has been reached or when the timeout expires -- effectively blending the built-in CountTrigger and EventTimeTrigger.
