title: mariadb master to master replication auto increment settings
body: <p>I have just made a maria db master to master replication and after few days, I realized following the tutorial now the auto increment is by 2 instead of 1 as normal.</p>
  
  <p>I am wondering, would it be save to set it back to 1? or it's the best to leave it at 2 instead of same id bumped to each other while creating rows.  That seeing id always increment by 2 would consider a healthy db too?</p>
