title: MySQL Single Primary Group Replication - auto_increment_increment
body: <p>I am setting up MySQL Group Replication with the following configuration</p>
  <ul>
  <li>1 Virtual IP</li>
  <li>2 ProxySQL</li>
  <li>3 MySQL Servers with Single Master Group Replication</li>
  </ul>
  <p>I understand why MySQL chose to use 7 as the default auto_increment_increment value (<a href="https://dev.mysql.com/blog-archive/mysql-group-replication-auto-increment-configuration-handling/" rel="nofollow noreferrer">link</a>), my question is</p>
  <ul>
  <li>Considering only one node will be responsible for the updates at any given point of time, is it safe to set auto_increment_increment value to 1 in my setup?</li>
  </ul>
