title: What is a buffer write?
body: <p>Can some help me understand what a buffer write is? I'm particularly interested in learning its function in the context database systems, MySQL say! Some of the following would be helpful:</p>
  
  <ol>
  <li>What is the purpose of a buffer write</li>
  <li>Are there any performance advantages</li>
  <li>An example of a buffer write in a database application</li>
  </ol>
  
  <p>I came across this term several times and I was unable to discern its meaning.</p>
  
  <p>Thanks</p>
