Dmitry Golubets updated FLINK-5652:
-----------------------------------
Description:
When async operation timeout is > 0, the number of StreamRecordQueueEntry
instances keeps growing.
It can be easily reproduced with the following code:
{code}
val src: DataStream[Int] = env.fromCollection((1 to Int.MaxValue).iterator)
val asyncFunction = new AsyncFunction[Int, Int] with Serializable {
override def asyncInvoke(input: Int, collector: AsyncCollector[Int]): Unit
= {
collector.collect(List(input))
}
}
AsyncDataStream.unorderedWait(src, asyncFunction, 1, TimeUnit.MINUTES,
1).print()
{code}
