@greghogan Excuse my ignorance, I'm only now learning about Flink internals
:)
It seems like the issue here was that `partitionByRange` partitions keys in
ascending order but we want the end result in descending order.
@tfournier314 I think the following should work, here I use a key extractor
to negate the value of the key to achieve the desired effect:
```Scala
itData.map(s => (s,1))
.groupBy(0)
.sum(1)
.partitionByRange(x => -x._2) // Take the negative count as the key
.sortPartition(1, Order.DESCENDING)
.zipWithIndex
```
