HBase is an open-source, distributed, versioned, column-oriented store modeled after Google's Bigtable. Yahoo! has been using HBase for a long time as isolated one off deployments. Having a multi-tenant platform makes it possible for all our grid customers to take advantage of HBase capabilities now. We will provide a brief overview of HBase and how it works (several of you asked for back to basics type talks), and then spend the majority of our time talking about multi-tenancy with HBase.
