title: mysql how to write the changes to memory first , then to disk
body: <p>is there a way to commit your transactions to memory first ? and then persist the same changes on the hard disk after some time , when the work load is not heavy? im talking about like 3-5 seconds maximum. I cannot risk holding all the database on memory , i just want to reflect the changes to memory first , so that i can have a quick response , with no delay caused by the harddisk. is there a way to do this without placing all the database on memory ? </p>
  
  <p>im using hibernate 3.6, mysql 5.1.22 and mysql connector 5.1.18. But i can change to mysql 5.5 if needed</p>
