Subject [jira] [Created] (HBASE-4256) Intra-row scanning (part deux)

Intra-row scanning (part deux)
------------------------------

                 Key: HBASE-4256
                 URL: https://issues.apache.org/jira/browse/HBASE-4256
             Project: HBase
          Issue Type: New Feature
    Affects Versions: 0.90.4
            Reporter: Jean-Daniel Cryans
            Priority: Critical
             Fix For: 0.94.0


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".
