-**Please note:** Since we're dealing with HBase (and not an OLTP data store), fitting a classical ORM paradigm may not make sense. So this library doesn't intend to evolve as a full-fledged ORM. However, if you do intend to use HBase via ORM, I suggest you use [Apache Phoenix](https://phoenix.apache.org/).
