This extension provides the [redis](http://redis.io/) key-value store support for the [Yii framework 2.0](http://www.yiiframework.com).
It includes a `Cache` and `Session` storage handler and implements the `ActiveRecord` pattern that allows
you to store active records in redis.
For license information check the [LICENSE](LICENSE.md)-file.
Documentation is at [docs/guide/README.md](docs/guide/README.md).
[![Latest Stable Version](https://poser.pugx.org/yiisoft/yii2-redis/v/stable.png)](https://packagist.org/packages/yiisoft/yii2-redis)

/**
* ActiveQuery represents a query associated with an Active Record class.
*
* An ActiveQuery can be a normal query or be used in a relational context.
*
* ActiveQuery instances are usually created by [[ActiveRecord::find()]].
* Relational queries are created by [[ActiveRecord::hasOne()]] and [[ActiveRecord::hasMany()]].
*
* Normal Query
* ------------
*
* ActiveQuery mainly provides the following methods to retrieve the query results:
*
* - [[one()]]: returns a single record populated with the first row of data.
* - [[all()]]: returns all records based on the query results.
* - [[count()]]: returns the number of records.
* - [[sum()]]: returns the sum over the specified column.
* - [[average()]]: returns the average over the specified column.
* - [[min()]]: returns the min over the specified column.
* - [[max()]]: returns the max over the specified column.
* - [[scalar()]]: returns the value of the first column in the first row of the query result.
* - [[exists()]]: returns a value indicating whether the query result has data or not.
*
* You can use query methods, such as [[where()]], [[limit()]] and [[orderBy()]] to customize the query options.
*
* ActiveQuery also provides the following additional query options:
*
* - [[with()]]: list of relations that this query should be performed with.
* - [[indexBy()]]: the name of the column by which the query result should be indexed.
* - [[asArray()]]: whether to return each record as an array.
*
* These options can be configured using methods of the same name. For example:
*
* ```php
* $customers = Customer::find()->with('orders')->asArray()->all();
* ```
*
* Relational query
* ----------------
*
* In relational context ActiveQuery represents a relation between two Active Record classes.
*
* Relational ActiveQuery instances are usually created by calling [[ActiveRecord::hasOne()]] and
* [[ActiveRecord::hasMany()]]. An Active Record class declares a relation by defining
* a getter method which calls one of the above methods and returns the created ActiveQuery object.
*
* A relation is specified by [[link]] which represents the association between columns
* of different tables; and the multiplicity of the relation is indicated by [[multiple]].
*
* If a relation involves a junction table, it may be specified by [[via()]].
* This methods may only be called in a relational context. Same is true for [[inverseOf()]], which
* marks a relation as inverse of another relation.
*

/**
* Redis Cache implements a cache application component based on [redis](http://redis.io/) key-value store.
*
* Redis Cache requires redis version 2.6.12 or higher to work properly.
*
* It needs to be configured with a redis [[Connection]] that is also configured as an application component.
* By default it will use the `redis` application component.
*
* See [[Cache]] manual for common cache operations that redis Cache supports.
*
* Unlike the [[Cache]], redis Cache allows the expire parameter of [[set]], [[add]], [[mset]] and [[madd]] to
* be a floating point number, so you may specify the time in milliseconds (e.g. 0.1 will be 100 milliseconds).
*
* To use redis Cache as the cache application component, configure the application as follows,
*
* ~~~
* [
* 'components' => [
* 'cache' => [
* 'class' => 'yii\redis\Cache',
* 'redis' => [
* 'hostname' => 'localhost',
* 'port' => 6379,
* 'database' => 0,
* ]
* ],
* ],
* ]
* ~~~
*
* Or if you have configured the redis [[Connection]] as an application component, the following is sufficient:
*
* ~~~
* [
* 'components' => [
* 'cache' => [
* 'class' => 'yii\redis\Cache',
* // 'redis' => 'redis' // id of the connection application component
* ],
* ],
* ]
* ~~~
*
* If you have multiple redis replicas (e.g. AWS ElasticCache Redis) you can configure the cache to
* send read operations to the replicas. If no replicas are configured, all operations will be performed on the
* master connection configured via the [[redis]] property.
*
* ~~~
* [
* 'components' => [
* 'cache' => [
* 'class' => 'yii\redis\Cache',
* 'enableReplicas' => true,
* 'replicas' => [
* // config for replica redis connections, (default class will be yii\redis\Connection if not provided)
* // you can optionally put in master as hostname as well, as all GET operation will use replicas
* 'redis',//id of Redis [[Connection]] Component
* ['hostname' => 'redis-slave-002.xyz.0001.apse1.cache.amazonaws.com'],
