This add-on uses Credis with a custom cache provider for Redis (based off Cm_Cache_Backend_Redis). For best performance, install the php extension: phpredis

You must have a Redis instance installed, this is likely not possible with shared hosting

While XenForo 2 has a redis connector, it requires phpredis. This add-on does not.

Feature overview
  • A pure php redis connector
  • High availability support
  • Exposes redis cache object for use for use by other add-ons
  • Implements some minor caching of forum thread counts

Please be aware that Redis is very sensitive to latency in a virtual environment. If repeated connection failures or protocol errors are experienced disable any Redis Persistence options.


Edit src/config.php and add:
$config['cache']['enabled'] = true;
$config['cache']['sessions'] = true;
$config['cache']['provider'] = 'SV\RedisCache\Redis';
$config['cache']['config'] = [
    'server' => '',
    'port' => 6379,

By default, forum thread counts are cached. In general, this is observable when moving large number of threads from one forum to another, and the total page counts are wrong.


Redis Statistics
Admincp dash board is extended with basic redis statistics:

Include redis timings when using the _debug=1 view for a page

Read Scaling

With the $config['cache']['config']['load_from_replica'] option, reads can be deferred to a singular replica instance. This takes all the options of 'config' (except the replicaconfig)

See the FAQ for configuration samples.

High availability

The Zend component support primary/replica setups with Redis Sentinel support. It does not support Redis multi-master clustering.
  • Additionally, this add-on implement caching of thread counts in a forum.
  • Redis Sentinel support for high-availability (see FAQ for details).
