Subject Re: Migrating Tables with primary key and foreign key from mysql to Hbae
Date Tue, 27 Mar 2012 19:13:40 GMT

HBase is not a relational database, it doesn't have foreign keys or
constraints. I'd suggest you familiarize yourself with HBase by
reading the refence manual[1] or buying the book[2].
