Description

The indexing of anonymous contacts might cause low indexing performance or analytics index size growth. You can solve these issues by disabling the indexing of anonymous contacts and their interactions.

Solution

To resolve the issue, proceed as follows:

• For Sitecore XP 8.1 Update-2 (rev. 160302):
  
  1. Download and install the hotfix: Sitecore CMS 8.1 rev. 160302 Hotfix 126216-2.zip

     Be aware that the hotfix was built for a specific Sitecore XP version and must not be installed on other Sitecore XP versions or in combination with other hotfixes. In case any other hotfixes have already been installed on a certain Sitecore XP instance, send a request for a compatibility check to Sitecore Support.

     Note that the ZIP file contents must be extracted to locate installation instructions and related files inside. The hotfixes must be installed on a CM instance and then synced with other instances using standard development practices.

  2. In the \App_Config\Include\Sitecore.ContentSearch.Analytics.config file, set the ContentSearch.Analytics.IndexAnonymousContacts setting value to false, as follows:
     

     <setting name="ContentSearch.Analytics.IndexAnonymousContacts" value="false"/>

• For Sitecore XP 8.1 Update-3 (rev. 160519) and XP 8.2.x:
  In the \App_Config\Include\Sitecore.ContentSearch.Analytics.config file, set the ContentSearch.Analytics.IndexAnonymousContacts setting value to false, as follows:
  

  <setting name="ContentSearch.Analytics.IndexAnonymousContacts" value="false"/>
