Configure Prefetch cache values

Version: 10.4

Applies to

Content Delivery, Content Management

Sitecore populates prefetch caches on application initialization and maintains those caches over the life of the application. To configure the Prefetch cache values:

  1. Create a patch file for cache size values. For example, custom.prefetch.config.

  2. Use rule-based configuration to target different environments. The following example sets custom Web database cache values for the Content Delivery role, and Master database cache values for the Content Management role:

    <configuration xmlns:patch="http://www.sitecore.net/xmlconfig/"
               xmlns:set="http://www.sitecore.net/xmlconfig/set/" xmlns:role="http://www.sitecore.net/xmlconfig/role/">
   <sitecore>
      <databases>

         <database id="master" role:require="ContentManagement or Standalone">
            <dataProviders>
               <dataProvider>
                  <param desc="headProvider">
                     <dataProvider>
                        <prefetch>
                           <cacheSize>1000MB</cacheSize>
                        </prefetch>
                     </dataProvider>
                  </param>
               </dataProvider>
            </dataProviders>
         </database>

         <database id="web" role:require="ContentDelivery or Standalone">
            <dataProviders>
               <dataProvider>
                  <param desc="headProvider">
                     <dataProvider>
                        <prefetch>
                           <cacheSize>1000MB</cacheSize>
                        </prefetch>
                     </dataProvider>
                  </param>
               </dataProvider>
             </dataProviders>
         </database>

      </databases>
   </sitecore>
</configuration>

  3. Deploy your configuration file to the <root>/App_Config/Includes folder. You can check your changes by visiting /sitecore/admin/showconfig.aspx and searching for patch:source="custom.prefetch.config".
