> Added section under Schema Design for "Number of Versions"
> The fact that HBase doesn't overwrite values (but versions them by time) is one of those
"obvious but not so obvious" topics, and it recently came up on the dist-list.  Added small
description of why this is important to consider for schema design, link to HColumnDescriptor
javadoc, with internal link to Data Model section.
