title: Which database is the most space efficient
body: <p>Current we are using Oracle to store logging information. One of the column is a blob that stores an XML payload. We archive the logging schema every week, but we still hit about > 1TB a week.</p>
  
  <p>Goal: Reduce space footprint of database</p>
  
  <p>Solution 1:
  Compress the XML payload before putting it into the BLOB. </p>
  
  <p>Solution 2:
  Look for a database (noSQL or other relational DB) that already compresses data on default. JDBC driver must be available. </p>
  
  <p>Anyone know a database that fits into solution 2? So that we do not need to modify the app, we just need to change the DB and update the JDBC drivers. </p>
