Generalized quota-queries (position, sum progression, etc.)
SYNOPSIS
#(signature)
DESCRIPTION
**This operator is a work in progress and should be used with care.**
This operator is an attempt to generalize RANK in two directions:
* Use a full SUMMARIZATION instead of hard-coding a ranking attribute via count()
* Providing a BY key so that summarizations can actually be done on sub-groups
EXAMPLE
# Compute linear progression of quantities by supplier number
!(alf quota supplies -- sid -- qty -- position count sum_qty "sum{ qty }")
