Jonathan Gray updated HBASE-1481:
---------------------------------
Fix Version/s: 0.20.1
Release Note: (was: Moving this new 'feature' to 0.21.0.)
This patch is actually against 0.20.1. Looks like release of it is going to
get pushed back a bit, so I'm for putting this in to 0.20.1 since it's such a
simple addition (and quite useful).
Patch also includes unit test. Going to look at making another patch that
actually adds this in to any built-in row counting mechanisms.
> Add fast row key only scanning

> Instead of requiring a user to set up a scanner with any column and scan the
> table to gather all row keys while ignoring the column value we should have a
> fast and lightweight scanner that for example takes a "null" for the column
> list and then simply returns only the matching keys of all non-empty or
> deleted rows. Filters should still be applicable.
