There are several situations where it would be useful to reverse the order of a dataset. This could be done more efficiently than a sort. The change would need to cover the following particular cases:
There is also opportunity for various optimizations - e.g., REVERSE(SORT())->SORT'
The objective of this project is to implement a REVERSE activity in HPCC Systems. The proposal for this project needs to describe the methods that would be used to perform the following:
For each example the rows will need to be sequentially output in reverse order. There is no random access to rows in the incoming row stream.
