    Description

      Dave Revell was asking on IRC today if there's a way to scan ranges of qualifiers within a row. That is, to be able to specify a start qualifier and an end qualifier so that the Get or Scan seeks directly to the first qualifier and stops at some point which can be predeterminate by a qualifier or simply a batch configuration (already exists).

      This is particularly useful for large rows with time-based qualifiers.

      Dave also mentioned that another popular database has such a feature that they call "column slices".
