Subject [jira] [Commented] (ACCUMULO-1258) scan -b XXX -e XXX -c YYY should find entries with CF of YYYabc instead of just CF=YYY

    [ https://issues.apache.org/jira/browse/ACCUMULO-1258?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13627995#comment-13627995

Keith Turner commented on ACCUMULO-1258:
----------------------------------------

bq. There are regex iterators to do that.

That would work.   I may return more than you want.  I do not think there is a way in the
shell to limit the regex to just the col fam?

A specialized iterator could possibly go faster for this operation than a regex.  Once the
iterator detects it passed the prefix, it could seek to the next row, then seek to the prefix
within the row.   This would only make difference on large rows.

> I was using 1.4.1 when this ability would have come in handy. Not sure if the title is
clear, the -c option should find prefixes instead of just exact matches. Maybe this idea doesn't
work when both CF and CQ are present? I'd like to hear opinions on this.
