Configure Redis Cluster for distributed caching

Version: 10.2

You can change the configuration of an existing Sitecore XC deployment to use your Redis Cluster to scale distributed caching. The default Sitecore XC deployment uses stand-alone Redis.

Configure Commerce Engine caching to use Redis Cluster

To change Commerce Engine caching configuration to use Redis Cluster:

In the config.json file of the Commerce Engine instance running the Authoring service, for example inetpub\wwwroot\CommerceAuthoring_Sc\wwwroot\config.json, in the "Caching" section, under "Redis", and then under "Options", update the "Configurations" property with the appropriate connection string.

Note

The connection string does not specify a database. Redis Cluster only supports one database, and uses database 0 by default.

For example:
RequestResponse
```
"Caching":  
       ...
           "Redis":  {
                      ...
                         "Options":  {
                                       "Configuration":  "<YOUR_REDIS_CLUSTER:PORT>",
                                       "instanceName:  "Redis"
```

Configure CE Connect caching to use Redis Cluster

To change CE Connect caching configuration to use Redis Cluster:

In the inetpub\wwwroot\<storefront>\App_Config\Include\Y.Commerce.Engine\Sitecore.Commerce.Engine.Connect.config file, in the Redis options configuration section, update the <configuration> settings with the appropriate connection string.

Note

You must remove the defaultDatabase=1 from the configuration. Redis Cluster only supports one database, and uses database 0 by default.

For example:

RequestResponse

<redis type="Sitecore.Commerce.Engine.Connect.RedisCacheSettings, Sitecore.Commerce.Engine.Connect.Caching">
          ...
           <options type="Sitecore.Commerce.Engine.Connect.CommerceRedisCacheOptions, Sitecore.Commerce.Engine.Connect.Caching">
            <configuration>YOUR_REDIS_CLUSTER,allowAdmin=true,syncTimeout=3600000</configuration>
            <instanceName>Redis</instanceName>
          </options>
        </redis>
