From the post:
We at Cloudera are big fans of HBase. We love the technology, we love the community and we’ve found that it’s a great fit for many applications. Successful uses of HBase have been well documented and as a result, many organizations are considering whether HBase is a good fit for some of their applications. The impetus for my talk and this follow up blog post is to clarify some of the good applications for HBase, warn against some poor applications and highlight important steps to a successful HBase deployment.
Helpful review of HBase.
