Subject [jira] [Comment Edited] (HBASE-9769) Improve performance of a Scanner with explicit column list when rows are small/medium size
Date Wed, 16 Oct 2013 02:39:42 GMT

----------------------------------------------------------------

Here's a *sample* of what I mean.
10 is hardcoded. Alternatively we could only do this when VERSIONS=1, so this way the user
would naturally provide a hint about how many version (s)he expects to keep and we use that
hint.
