title: When is it an overkill to use Hadoop?
body: <p>I have an Oracle database (roughly 1.2 billion records) of data with a web application sitting on top of it that generates queries (generates SQL code and returns counts). Basically you generated SQL queries graphically through an AJAX UI...and it runs pretty nice performance-wise.</p>
  
  <p>This is roughly a 400 GB database. I've been looking at Hadoop and thinking about using it instead of Oracle (have my app generate HIVE query code), BUT it seems to me like it's an overkill....isn't hadoop targeted more towards tens of terabytes to petabyte scale datasets? Is it suitable in place of a relational database (like Oracle) for the task I'm doing??</p>
