Lars Hofhansl commented on HBASE-4256:
--------------------------------------
I still think being able to start a scanner at a column would be a helpful
addition. We had a use case for that with wide tables in one of our POCs, but
then reworked the problem. Not sure how general this usecase would be, though.

> 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".
