title: xtradb vs innodb
body: <p>I was asked to check Mariadb as Centos does not provider MySQL 5.5 for the moment. I have read that xtradb servers as a drop in for innodb. </p>
  
  <p>What are the advantages of using one or the other because if they were equal, they would not have been called the same name?</p>
  
  <p>Do you think that I should switch to Mariadb? What kind of problems I might face in the future because of updates if any.</p>
  
  <p>I know that the founder of MySQL is behind Mariadb, and Oracle is managing MySQL now. It seems a bit tricky as a tricky decision.</p>
  
  <p>Thank you in advance for your opinion,</p>
  
  <p><strong>Update,</strong> I asked the question here, because google did not display any recent updates. Only some old comparisons published prior to 2012</p>
