<p class="MsoNormal">Clustering works differently for authoring and runtime data. For authoring, the workbench (using helix / zookeeper) will make sure that any change to the (internal) git repositories (that is holding all your project assets) is distributed
in the cluster. For runtime data, you need to make sure you are using the same database. The server instances themselves are stateless, they get and store their information from/in the database for each request.<o:p></o:p></p>
