eArc-data-redis

Redis bridge providing entity-caching for the earc/data abstraction.

installation

Install the earc/data-redis library via composer.

$ composer require earc/data-redis

basic usage

Initialize the earc/data abstraction in your index.php, bootstrap or configuration script.

use eArc\Data\Initializer;

Initializer::init();

Then register the earc/data-redis bridge to the earc/data onLoad, onPersit and onRemove events.

use eArc\Data\ParameterInterface;
use eArc\DataRedis\RedisDataBridge;

// The order of the on load tagging is important!
di_tag(ParameterInterface::TAG_ON_LOAD, RedisDataBridge::class);
di_tag(ParameterInterface::TAG_ON_LOAD, MyDatabaseBridge::class);

di_tag(ParameterInterface::TAG_ON_PERSIST, RedisDataBridge::class);
di_tag(ParameterInterface::TAG_ON_PERSIST, MyDatabaseBridge::class);

di_tag(ParameterInterface::TAG_ON_REMOVE, RedisDataBridge::class);
di_tag(ParameterInterface::TAG_ON_REMOVE, MyDatabaseBridge::class);

Important: For the onLoad event you have to tag the RedisDataBridge before your database bridge. Otherwise, the entities will never be loaded from cache.

Now earc/data uses your redis server to cache your entities.

connection parameter for redis

By default, earc/data-redis uses localhost and the defaults of the php-redis-extension. You can overwrite these defaults:

use eArc\DataRedis\ParameterInterface;

di_set_param(ParameterInterface::REDIS_CONNECTION, ['127.0.0.1', 6379]);

This array is handed to the Redis::connect() method as arguments. Consult the phpredis documentation for valid values and configuration options.

advanced usage

earc/data-redis uses redis hashes to cache your entities. By default, the hash-keys are prefixed by earc-data. If you need another prefix to manage the redis namespace, you can overwrite the default:

use eArc\DataRedis\ParameterInterface;

di_set_param(ParameterInterface::HASH_KEY_PREFIX, 'some-hash-key-prefix');
