I am evaluating if HBase is right for a small prototype I am developing. Please help me understand a few things:
1. Can I do something like this in RDBMS -- "select * from table WHERE column LIKE '%xyz%'" 2. How should we place constraints? For example, if I have a Users table, and one column is "login_name". How can I ensure that no two people create the same login name? Is there a constraint I can place or something similar? 3. Is there something with HBase tables that I CANNOT do? If there is, what is the strategy I have to use? 4. For something not possible with HBase today, can I simply use the MapReduce framework that comes with Hadoop over the HBase tables?
