Yahoo! has been using HBase for a long time in isolated instances, most notably for the personalization platform powering its homepage experiences. The introduction of multi-tenancy has lowered the barriers for all Hadoop users to use HBase. We will cover traditional use cases for HBase at Yahoo!, and new use cases as a result in content management, advertising, log processing, analytics and reporting, recommendation graphs, and dimension data stores.

We will then talk about the deployment strategy and enhancements made that facilitate multi-tenancy. Region Server groups provide a coarse level of isolation among tenants by designating a subset of region servers to serve designated tables, and Namespaces for logical grouping of resources (region servers, tables) and privileges (quota, ACLs).

We'll also share our experiences in operating HBase with security enabled and contributions made in this area, and results from performance runs conducted to validate customer expectations in a multi-tenant environment.
