Cache

Provides a standardized interface to implement caching and shared memory mechanisms into an App by connecting to multiple external cache providers.

See the Cache guide to learn how to work with the Cache module.

Configuration

• providers A hash array of the available cache providers, where the key is the name of the cache provider, and the value is a hash array with the following possible keys:

  • providerClassName The name of the cache provider class, from the available ones:

    • CacheProviderApc

    • CacheProviderApcu

    • CacheProviderMemcached

    • CacheProviderRedis

  • config A hash array of configuration options for the cache provider, where each different cache provider has different available config keys:

    • For CacheProviderApc: No configuration needed.

    • For CacheProviderApcu: No configuration needed.

    • For CacheProviderMemcached:

      • isPersistentConnection

      • isCompression

      • servers An array of the servers to add to the server Memcached pool, as documented in https://www.php.net/manual/en/memcached.addservers.php

    • For CacheProviderRedis:

      • scheme The connection scheme. Default: tcp

      • host The host name or IP of the Redis server. Default: localhost

      • port The server port. Default: 6379

      • database The Redis database number to use. Default: 0

      • prefix The prefix to use for all cache keys. Used to avoid key collisions with other apps that might be running in the server. Defaults to none.

      • isPersistentConnection Whether to keep the connection to Redis active between requests. Default: true
