checkpoint state keeps on increasing

[Janardhan Reddy]

Hi,

I am noticing that the checkpointing state has been constantly growing for
the below subtask. Only the current active window elements should be
checkpointed ? why is it constantly growing ?

finalStream.keyBy("<>").countWindow(2,1)
  .apply((_, _, input: scala.Iterable[], out: Collector[]) => {
    val inputArray = input.toArray

... do something

}
