## Cluster
Redis Cluster provides a way to run a Redis installation where data is automatically sharded across multiple Redis nodes.
You can connect to a Redis Cluster like this:
```javascript
var Redis = require('ioredis');
var cluster = new Redis.Cluster([{
port: 6380,
host: '127.0.0.1'
}, {

## Pipelining
If you want to send a batch of commands (e.g. > 5), you can use pipelining to queue
the commands in memory and then send them to Redis all at once. This way the performance improves by 50%~300% (See [benchmark section
](#benchmark)).
`redis.pipeline()` creates a `Pipeline` instance. You can call any Redis
commands on it just like the `Redis` instance. The commands are queued in memory
and flushed to Redis by calling the `exec` method:
```javascript
var pipeline = redis.pipeline();
pipeline.set('foo', 'bar');
pipeline.del('cc');
...print = function (err, reply) {
if (err) {
console.log('Error: ' + err);
} else {
console.log('Reply: ' + reply);
}

`retryStrategy` is a function that will be called when the connection is lost.
The argument `times` means this is the nth reconnection being made and
the return value represents how long (in ms) to wait to reconnect. When the
return value isn't a number, ioredis will stop trying to reconnect, and the connection
will be lost forever if the user doesn't call `redis.connect()` manually.
When reconnected, the client will auto subscribe to channels that the previous connection subscribed to.
This behavior can be disabled by setting the `autoResubscribe` option to `false`.
And if the previous connection has some unfulfilled commands (most likely blocking commands such as `brpop` and `blpop`),
the client will resend them when reconnected. This behavior can be disabled by setting the `autoResendUnfulfilledCommands` option
to `false`.

`redis.pipeline()` creates a `Pipeline` instance. You can call any Redis
commands on it just like the `Redis` instance. The commands are queued in memory
and flushed to Redis by calling the `exec` method:
```javascript
var pipeline = redis.pipeline();
pipeline.set('foo', 'bar');
pipeline.del('cc');
pipeline.exec(function (err, results) {
// `err` is always null, and `results` is an array of responses
// corresponding to the sequence of queued commands.
// Each response follows the format `[err, result]`.
});
// You can even chain the commands:

## Auto-reconnect
By default, ioredis will try to reconnect when the connection to Redis is lost
except when the connection is closed manually by `redis.disconnect()` or `redis.quit()`.
It's very flexible to control how long to wait to reconnect after disconnection
using the `retryStrategy` option:
```javascript
var redis = new Redis({
// This is the default value of `retryStrategy`

## Basic Usage
```javascript
var Redis = require('ioredis');
var redis = new Redis();
redis.set('foo', 'bar');
redis.get('foo', function (err, result) {
console.log(result);
});
// Or using a promise if the last argument isn't a function
redis.get('foo').then(function (result) {
console.log(result);
});
...getBuffer = function () {
var firstArgIndex = 0;
var commandName = _commandName;
if (commandName === null) {
commandName = arguments[0];
firstArgIndex = 1;
}
var length = arguments.length;
var lastArgIndex = length - 1;
var callback = arguments[lastArgIndex];
if (typeof callback !== 'function') {
callback = undefined;
} else {
length = lastArgIndex;
}
var args = new Array(length - firstArgIndex);
for (var i = firstArgIndex; i < length; ++i) {
args[i - firstArgIndex] = arguments[i];
}
var options;
if (this.options.dropBufferSupport) {
if (!_encoding) {
return Promise.reject(new Error(DROP_BUFFER_SUPPORT_ERROR)).nodeify(callback);
}
options = { replyEncoding: null };
} else {
options = { replyEncoding: _encoding };
}
if (this.options.showFriendlyErrorStack) {
options.errorStack = new Error().stack;
}
if (this.options.keyPrefix) {
options.keyPrefix = this.options.keyPrefix;
}
return this.sendCommand(new Command(commandName, args, options, callback));
}...
redis.set('foo', new Buffer('bar'));
```
And every command has a method that returns a Buffer (by adding a suffix of "Buffer" to the command name).
To get a buffer instead of a utf8 string:
```javascript
redis.getBuffer('foo', function (err, result) {
// result is a buffer.
});
```
## Pipelining
If you want to send a batch of commands (e.g. > 5), you can use pipelining to queue
the commands in memory and then send them to Redis all at once. This way the performance improves by 50%~300% (See [benchmark section
](#benchmark)).

Just like other commands, `scanStream` has a binary version `scanBufferStream`, which returns an array of buffers. It's useful
when
the key names are not utf8 strings.
There are also `hscanStream`, `zscanStream` and `sscanStream` to iterate through elements in a hash, zset and set. The interface
of each is
similar to `scanStream` except the first argument is the key name:
```javascript
var stream = redis.hscanStream('myhash', {
match: 'age:??'
});
```
You can learn more from the [Redis documentation](http://redis.io/commands/scan).

a reply transformer for `hgetall`. Transformers for `hmset` and `hgetall` were mentioned
above, and the transformer for `mset` is similar to the one for `hmset`:
```javascript

redis.get('k1', function (err, result) {
// result === 'v1';
});
redis.mset(new Map([['k3', 'v3'], ['k4', 'v4']]));

## Transaction
Most of the time, the transaction commands `multi` & `exec` are used together with pipeline.
Therefore, when `multi` is called, a `Pipeline` instance is created automatically by default,
so you can use `multi` just like `pipeline`:
```javascript
redis.multi().set('foo', 'bar').get('foo').exec(function
(err, results) {
// results === [[null, 'OK'], [null, 'bar']]
});
```
If there's a syntax error in the transaction's command chain (e.g. wrong number of arguments, wrong command name, etc),
then none of the commands would be executed, and an error is returned:
```javascript
...multiBuffer = function () {
var firstArgIndex = 0;
var commandName = _commandName;
if (commandName === null) {
commandName = arguments[0];
firstArgIndex = 1;
}
var length = arguments.length;
var lastArgIndex = length - 1;
var callback = arguments[lastArgIndex];
if (typeof callback !== 'function') {
callback = undefined;
} else {
length = lastArgIndex;
}
var args = new Array(length - firstArgIndex);
for (var i = firstArgIndex; i < length; ++i) {
args[i - firstArgIndex] = arguments[i];
}
var options;
if (this.options.dropBufferSupport) {
if (!_encoding) {
return Promise.reject(new Error(DROP_BUFFER_SUPPORT_ERROR)).nodeify(callback);
}
options = { replyEncoding: null };
} else {
options = { replyEncoding: _encoding };
}
if (this.options.showFriendlyErrorStack) {
options.errorStack = new Error().stack;
}
if (this.options.keyPrefix) {

nodes = function (role) {
role = role || 'all';
if (role !== 'all' && role !== 'master' && role !== 'slave') {
throw new Error('Invalid role "' + role + '". Expected "all", "master" or "slave"');
}
return _.values(this.connectionPool.nodes[role]);
}...
Sometimes you may want to send a command to multiple nodes (masters or slaves) of the cluster, you can get the nodes via `Cluster
#nodes()` method.
`Cluster#nodes()` accepts a parameter role, which can be "master", "slave" and "all" (default), and
returns an array of `Redis` instance. For example:
```javascript
// Send `FLUSHDB` command to all slaves:
var slaves = cluster.nodes('slave');
Promise.all(slaves.map(function (node) {
return node.flushdb();
}));
// Get keys of all the masters:
var masters = cluster.nodes('master');
Promise.all(masters.map(function (node) {

## Pipelining
If you want to send a batch of commands (e.g. > 5), you can use pipelining to queue
the commands in memory and then send them to Redis all at once. This way the performance improves by 50%~300% (See [benchmark section
](#benchmark)).
`redis.pipeline()` creates a `Pipeline` instance. You can call any Redis
commands on it just like the `Redis` instance. The commands are queued in memory
and flushed to Redis by calling the `exec` method:
```javascript
var pipeline = redis.pipeline();
pipeline.set('foo', 'bar');
pipeline.del('cc');

`PSUBSCRIBE` is also supported in a similar way:
```javascript
redis.psubscribe('pat?ern', function (err, count) {});
redis.on('pmessage', function (pattern, channel, message) {});
redis.on('pmessageBuffer', function (pattern, channel, message) {});
```
When a client issues a SUBSCRIBE or PSUBSCRIBE, that connection is put into a "subscriber" mode.
At that point, only commands that modify the subscription set are valid.
When the subscription set is empty, the connection is put back into regular mode.

## Auto-reconnect
By default, ioredis will try to reconnect when the connection to Redis is lost
except when the connection is closed manually by `redis.disconnect()` or `redis.quit()`.
It's very flexible to control how long to wait to reconnect after disconnection
using the `retryStrategy` option:
```javascript
var redis = new Redis({
// This is the default value of `retryStrategy`
...quitBuffer = function () {
var firstArgIndex = 0;
var commandName = _commandName;

default, this option is disabled and can only be used for debugging purposes. You **shouldn't** use this feature in a production

```javascript

// you can log the error here.
// error.command.name is the command name, here is 'set'

* **cluster:** support scaling reads to slaves ([98bdec2](https://github.com/luin/ioredis/commit/98bdec2)), closes [#170](https://
github.com/luin/ioredis/issues/170)
* **redis:** support readonly mode for cluster ([0a4186e](https://github.com/luin/ioredis/commit/0a4186e))
### BREAKING CHANGES
* **cluster:** `Cluster#masterNodes` and `Cluster#nodes` is removed. Use `Cluster#nodes('masters')` and `Cluster#nodes
('all')` instead.
* **cluster:** `Cluster#to()` is removed. Use `Promise.all(Cluster#nodes().map(function
(node) {}))` instead.
* **cluster:** Option `readOnly` is removed. Check out `scaleReads` option.

Besides auto-reconnect when the connection is closed, ioredis supports reconnecting on the specified errors by the `reconnectOnError
` option. Here's an example that will reconnect when receiving `READONLY` error:
```javascript
var redis = new Redis({
reconnectOnError: function (err) {
var targetError = 'READONLY';
if (err.message.slice(0, targetError.length) === targetError) {
// Only reconnect when the error starts with "READONLY"
return true; // or `return 1;`
}
}
});

care of script caching and to detect when to use `EVAL` and when to use `EVALSHA`.
ioredis expose a `defineCommand` method to make scripting much easier to use:
```javascript
var redis = new Redis();
// This will define a command echo:
redis.defineCommand('echo', {
numberOfKeys: 2,
lua: 'return {KEYS[1],KEYS[2],ARGV[1],ARGV[2]}'
});
// Now `echo` can be used just like any other ordinary command,
// and ioredis will try to use `EVALSHA` internally when possible for better performance.

`redis.pipeline()` creates a `Pipeline` instance. You can call any Redis
commands on it just like the `Redis` instance. The commands are queued in memory
and flushed to Redis by calling the `exec` method:
```javascript
var pipeline = redis.pipeline();
pipeline.set('foo', 'bar');
pipeline.del('cc');
pipeline.exec(function (err, results) {
// `err` is always null, and `results` is an array of responses
// corresponding to the sequence of queued commands.
// Each response follows the format `[err, result]`.
});
// You can even chain the commands:

`Cluster#nodes()` accepts a parameter role, which can be "master", "slave" and "all" (default), and
returns an array of `Redis` instance. For example:
```javascript
// Send `FLUSHDB` command to all slaves:
var slaves = cluster.nodes('slave');
Promise.all(slaves.map(function (node) {
return node.flushdb();
}));
// Get keys of all the masters:
var masters = cluster.nodes('master');
Promise.all(masters.map(function (node) {
return node.keys();
})).then(function (keys) {

## Basic Usage
```javascript
var Redis = require('ioredis');
var redis = new Redis();
redis.set('foo', 'bar');
redis.get('foo', function (err, result) {
console.log(result);
});
// Or using a promise if the last argument isn't a function
redis.get('foo').then(function (result) {
console.log(result);
});
...getBuffer = function () {
var firstArgIndex = 0;
var commandName = _commandName;
if (commandName === null) {
commandName = arguments[0];
firstArgIndex = 1;
}
var length = arguments.length;
var lastArgIndex = length - 1;
var callback = arguments[lastArgIndex];
if (typeof callback !== 'function') {
callback = undefined;
} else {
length = lastArgIndex;
}
var args = new Array(length - firstArgIndex);
for (var i = firstArgIndex; i < length; ++i) {
args[i - firstArgIndex] = arguments[i];
}
var options;
if (this.options.dropBufferSupport) {
if (!_encoding) {
return Promise.reject(new Error(DROP_BUFFER_SUPPORT_ERROR)).nodeify(callback);
}
options = { replyEncoding: null };
} else {
options = { replyEncoding: _encoding };
}
if (this.options.showFriendlyErrorStack) {
options.errorStack = new Error().stack;
}
if (this.options.keyPrefix) {
options.keyPrefix = this.options.keyPrefix;
}
return this.sendCommand(new Command(commandName, args, options, callback));
}...
redis.set('foo', new Buffer('bar'));
```
And every command has a method that returns a Buffer (by adding a suffix of "Buffer" to the command name).
To get a buffer instead of a utf8 string:
```javascript
redis.getBuffer('foo', function (err, result) {
// result is a buffer.
});
```
## Pipelining
If you want to send a batch of commands (e.g. > 5), you can use pipelining to queue
the commands in memory and then send them to Redis all at once. This way the performance improves by 50%~300% (See [benchmark section
](#benchmark)).

There are three built-in transformers, two argument transformers for `hmset` & `mset` and
a reply transformer for `hgetall`. Transformers for `hmset` and `hgetall` were mentioned
above, and the transformer for `mset` is similar to the one for `hmset`:
```javascript
redis.mset({ k1: 'v1', k2: 'v2' });
redis.get('k1', function (err, result) {
// result === 'v1';
});
redis.mset(new Map([['k3', 'v3'], ['k4', 'v4']]));
redis.get('k3', function (err, result) {
// result === 'v3';

## Transaction
Most of the time, the transaction commands `multi` & `exec` are used together with pipeline.
Therefore, when `multi` is called, a `Pipeline` instance is created automatically by default,
so you can use `multi` just like `pipeline`:
```javascript
redis.multi().set('foo', 'bar').get('foo').exec(function
(err, results) {
// results === [[null, 'OK'], [null, 'bar']]
});
```
If there's a syntax error in the transaction's command chain (e.g. wrong number of arguments, wrong command name, etc),
then none of the commands would be executed, and an error is returned:
```javascript

var firstArgIndex = 0;

// Both `channel` and `message` are buffers.
});
```
`PSUBSCRIBE` is also supported in a similar way:
```javascript
redis.psubscribe('pat?ern', function (err, count) {});
redis.on('pmessage', function (pattern, channel, message) {});
redis.on('pmessageBuffer', function (pattern, channel, message) {});
```
When a client issues a SUBSCRIBE or PSUBSCRIBE, that connection is put into a "subscriber" mode.
At that point, only commands that modify the subscription set are valid.
When the subscription set is empty, the connection is put back into regular mode.

You can learn more from the [Redis documentation](http://redis.io/commands/scan).
## Auto-reconnect
By default, ioredis will try to reconnect when the connection to Redis is lost
except when the connection is closed manually by `redis.disconnect()` or `redis.quit()`.
It's very flexible to control how long to wait to reconnect after disconnection
using the `retryStrategy` option:
```javascript
var redis = new Redis({
// This is the default value of `retryStrategy`
...quitBuffer = function () {
var firstArgIndex = 0;
var commandName = _commandName;
if (commandName === null) {
commandName = arguments[0];

var lastArgIndex = length - 1;
var callback = arguments[lastArgIndex];
if (typeof callback !== 'function') {

} else {

`retryStrategy` is a function that will be called when the connection is lost.
The argument `times` means this is the nth reconnection being made and
the return value represents how long (in ms) to wait to reconnect. When the
return value isn't a number, ioredis will stop trying to reconnect, and the connection
will be lost forever if the user doesn't call `redis.connect()` manually.
When reconnected, the client will auto subscribe to channels that the previous connection subscribed to.
This behavior can be disabled by setting the `autoResubscribe` option to `false`.
And if the previous connection has some unfulfilled commands (most likely blocking commands such as `brpop` and `blpop`),
the client will resend them when reconnected. This behavior can be disabled by setting the `autoResendUnfulfilledCommands` option
to `false`.
...disconnect = function () {
this.connecting = false;
if (this.stream) {
this.stream.end();
}
}...
});
```
You can learn more from the [Redis documentation](http://redis.io/commands/scan).
## Auto-reconnect
By default, ioredis will try to reconnect when the connection to Redis is lost
except when the connection is closed manually by `redis.disconnect()` or `redis.quit()`.
It's very flexible to control how long to wait to reconnect after disconnection
using the `retryStrategy` option:
```javascript
var redis = new Redis({
// This is the default value of `retryStrategy`
...retryStrategy = function (times) {
return Math.min(times * 2, 2000);
}...
return close();
}
if (typeof self.options.retryStrategy !== 'function') {
debug('skip reconnecting because `retryStrategy` is not a function');
return close();
}
var retryDelay = self.options.retryStrategy(++self.retryAttempts);
if (typeof retryDelay !== 'number') {
debug('skip reconnecting because `retryStrategy` doesn\'t return a number');
return close();
}
debug('reconnect in %sms', retryDelay);
...sentinelRetryStrategy = function (times) {
return Math.min(times * 10, 1000);
}...
function connectToNext() {
_this.currentPoint += 1;
if (_this.currentPoint === _this.sentinels.length) {
_this.currentPoint = -1;
var retryDelay;
if (typeof _this.options.sentinelRetryStrategy === 'function') {
retryDelay = _this.options.sentinelRetryStrategy(++_this.retryAttempts);
}
if (typeof retryDelay !== 'number') {

## Pipelining
If you want to send a batch of commands (e.g. > 5), you can use pipelining to queue
the commands in memory and then send them to Redis all at once. This way the performance improves by 50%~300% (See [benchmark section
](#benchmark)).
`redis.pipeline()` creates a `Pipeline` instance. You can call any Redis
commands on it just like the `Redis` instance. The commands are queued in memory
and flushed to Redis by calling the `exec` method:
```javascript
var pipeline = redis.pipeline();
pipeline.set('foo', 'bar');
pipeline.del('cc');
...addBatch = function (commands) {
for (var i = 0; i < commands.length; ++i) {
var command = commands[i];
var commandName = command.shift();
this[commandName].apply(this, command);
}
return this;

care of script caching and to detect when to use `EVAL` and when to use `EVALSHA`.
ioredis expose a `defineCommand` method to make scripting much easier to use:
```javascript

// This will define a command echo:
redis.defineCommand('echo', {
numberOfKeys: 2,
lua: 'return {KEYS[1],KEYS[2],ARGV[1],ARGV[2]}'
});
// Now `echo` can be used just like any other ordinary command,
// and ioredis will try to use `EVALSHA` internally when possible for better performance.

`redis.pipeline()` creates a `Pipeline` instance. You can call any Redis
commands on it just like the `Redis` instance. The commands are queued in memory
and flushed to Redis by calling the `exec` method:
```javascript
var pipeline = redis.pipeline();
pipeline.set('foo', 'bar');
pipeline.del('cc');
pipeline.exec(function (err, results) {
// `err` is always null, and `results` is an array of responses
// corresponding to the sequence of queued commands.
// Each response follows the format `[err, result]`.
});
// You can even chain the commands:

and flushed to Redis by calling the `exec` method:
```javascript

pipeline.exec(function (err, results) {
// `err` is always null, and `results` is an array of responses
// corresponding to the sequence of queued commands.
// Each response follows the format `[err, result]`.
});
// You can even chain the commands:
redis.pipeline().set('foo', 'bar').del('cc').exec(function (err, results) {

## Basic Usage
```javascript
var Redis = require('ioredis');
var redis = new Redis();
redis.set('foo', 'bar');
redis.get('foo', function (err, result) {
console.log(result);
});
// Or using a promise if the last argument isn't a function
redis.get('foo').then(function (result) {
console.log(result);
});
...getBuffer = function () {
var firstArgIndex = 0;
var commandName = _commandName;
if (commandName === null) {
commandName = arguments[0];
firstArgIndex = 1;
}
var length = arguments.length;
var lastArgIndex = length - 1;
var callback = arguments[lastArgIndex];
if (typeof callback !== 'function') {
callback = undefined;
} else {
length = lastArgIndex;
}
var args = new Array(length - firstArgIndex);
for (var i = firstArgIndex; i < length; ++i) {
args[i - firstArgIndex] = arguments[i];
}
var options;
if (this.options.dropBufferSupport) {
if (!_encoding) {
return Promise.reject(new Error(DROP_BUFFER_SUPPORT_ERROR)).nodeify(callback);
}
options = { replyEncoding: null };
} else {
options = { replyEncoding: _encoding };
}
if (this.options.showFriendlyErrorStack) {
options.errorStack = new Error().stack;
}
if (this.options.keyPrefix) {
options.keyPrefix = this.options.keyPrefix;
}
return this.sendCommand(new Command(commandName, args, options, callback));
}...
redis.set('foo', new Buffer('bar'));
```
And every command has a method that returns a Buffer (by adding a suffix of "Buffer" to the command name).
To get a buffer instead of a utf8 string:
```javascript
redis.getBuffer('foo', function (err, result) {
// result is a buffer.
});
```
## Pipelining
If you want to send a batch of commands (e.g. > 5), you can use pipelining to queue
the commands in memory and then send them to Redis all at once. This way the performance improves by 50%~300% (See [benchmark section
](#benchmark)).

## Transaction
Most of the time, the transaction commands `multi` & `exec` are used together with pipeline.
Therefore, when `multi` is called, a `Pipeline` instance is created automatically by default,
so you can use `multi` just like `pipeline`:
```javascript
redis.multi().set('foo', 'bar').get('foo').exec(function
(err, results) {
// results === [[null, 'OK'], [null, 'bar']]

// Both `channel` and `message` are buffers.
});
```
`PSUBSCRIBE` is also supported in a similar way:
```javascript
redis.psubscribe('pat?ern', function (err, count) {});
redis.on('pmessage', function (pattern, channel, message) {});
redis.on('pmessageBuffer', function (pattern, channel, message) {});
```
When a client issues a SUBSCRIBE or PSUBSCRIBE, that connection is put into a "subscriber" mode.
At that point, only commands that modify the subscription set are valid.
When the subscription set is empty, the connection is put back into regular mode.

## Auto-reconnect
By default, ioredis will try to reconnect when the connection to Redis is lost
except when the connection is closed manually by `redis.disconnect()` or `redis.quit()`.
It's very flexible to control how long to wait to reconnect after disconnection
using the `retryStrategy` option:
```javascript
var redis = new Redis({
// This is the default value of `retryStrategy`
...quitBuffer = function () {
var firstArgIndex = 0;
var commandName = _commandName;
if (commandName === null) {
commandName = arguments[0];

## Cluster
Redis Cluster provides a way to run a Redis installation where data is automatically sharded across multiple Redis nodes.
You can connect to a Redis Cluster like this:
```javascript
var Redis = require('ioredis');
var cluster = new Redis.Cluster([{
port: 6380,
host: '127.0.0.1'
}, {
port: 6381,
host: '127.0.0.1'
}]);

`retryStrategy` is a function that will be called when the connection is lost.
The argument `times` means this is the nth reconnection being made and
the return value represents how long (in ms) to wait to reconnect. When the
return value isn't a number, ioredis will stop trying to reconnect, and the connection
will be lost forever if the user doesn't call `redis.connect()` manually.
When reconnected, the client will auto subscribe to channels that the previous connection subscribed to.
This behavior can be disabled by setting the `autoResubscribe` option to `false`.
And if the previous connection has some unfulfilled commands (most likely blocking commands such as `brpop` and `blpop`),
the client will resend them when reconnected. This behavior can be disabled by setting the `autoResendUnfulfilledCommands` option
to `false`.

`redis.pipeline()` creates a `Pipeline` instance. You can call any Redis
commands on it just like the `Redis` instance. The commands are queued in memory
and flushed to Redis by calling the `exec` method:
```javascript
var pipeline = redis.pipeline();
pipeline.set('foo', 'bar');
pipeline.del('cc');
pipeline.exec(function (err, results) {
// `err` is always null, and `results` is an array of responses
// corresponding to the sequence of queued commands.
// Each response follows the format `[err, result]`.
});
// You can even chain the commands:

## Auto-reconnect
By default, ioredis will try to reconnect when the connection to Redis is lost
except when the connection is closed manually by `redis.disconnect()` or `redis.quit()`.
It's very flexible to control how long to wait to reconnect after disconnection
using the `retryStrategy` option:
```javascript
var redis = new Redis({
// This is the default value of `retryStrategy`

## Basic Usage
```javascript
var Redis = require('ioredis');
var redis = new Redis();
redis.set('foo', 'bar');
redis.get('foo', function (err, result) {
console.log(result);
});
// Or using a promise if the last argument isn't a function
redis.get('foo').then(function (result) {
console.log(result);
});
...getBuffer = function () {
var firstArgIndex = 0;
var commandName = _commandName;
if (commandName === null) {
commandName = arguments[0];
firstArgIndex = 1;
}
var length = arguments.length;
var lastArgIndex = length - 1;
var callback = arguments[lastArgIndex];
if (typeof callback !== 'function') {
callback = undefined;
} else {
length = lastArgIndex;
}
var args = new Array(length - firstArgIndex);
for (var i = firstArgIndex; i < length; ++i) {
args[i - firstArgIndex] = arguments[i];
}
var options;
if (this.options.dropBufferSupport) {
if (!_encoding) {
return Promise.reject(new Error(DROP_BUFFER_SUPPORT_ERROR)).nodeify(callback);
}
options = { replyEncoding: null };
} else {
options = { replyEncoding: _encoding };
}
if (this.options.showFriendlyErrorStack) {
options.errorStack = new Error().stack;
}
if (this.options.keyPrefix) {
options.keyPrefix = this.options.keyPrefix;
}
return this.sendCommand(new Command(commandName, args, options, callback));
}...
redis.set('foo', new Buffer('bar'));
```
And every command has a method that returns a Buffer (by adding a suffix of "Buffer" to the command name).
To get a buffer instead of a utf8 string:
```javascript
redis.getBuffer('foo', function (err, result) {
// result is a buffer.
});
```
## Pipelining
If you want to send a batch of commands (e.g. > 5), you can use pipelining to queue
the commands in memory and then send them to Redis all at once. This way the performance improves by 50%~300% (See [benchmark section
](#benchmark)).

Just like other commands, `scanStream` has a binary version `scanBufferStream`, which returns an array of buffers. It's useful
when
the key names are not utf8 strings.
There are also `hscanStream`, `zscanStream` and `sscanStream` to iterate through elements in a hash, zset and set. The interface
of each is
similar to `scanStream` except the first argument is the key name:
```javascript
var stream = redis.hscanStream('myhash', {
match: 'age:??'
});
```
You can learn more from the [Redis documentation](http://redis.io/commands/scan).

The `monitor` method returns a monitor instance.
After you send the MONITOR command, no other commands are valid on that connection. ioredis will emit a monitor event for every
new monitor message that comes across.
The callback for the monitor event takes a timestamp from the Redis server and an array of command arguments.
Here is a simple example:
```javascript
redis.monitor(function (err, monitor) {
monitor.on('monitor', function (time, args, source, database) {
});
});
```
## Streamify Scanning
Redis 2.8 added the `SCAN` command to incrementally iterate through the keys in the database. It's different from `KEYS` in
that

## Transaction
Most of the time, the transaction commands `multi` & `exec` are used together with pipeline.
Therefore, when `multi` is called, a `Pipeline` instance is created automatically by default,
so you can use `multi` just like `pipeline`:
```javascript
redis.multi().set('foo', 'bar').get('foo').exec(function
(err, results) {
// results === [[null, 'OK'], [null, 'bar']]
});
```
If there's a syntax error in the transaction's command chain (e.g. wrong number of arguments, wrong command name, etc),
then none of the commands would be executed, and an error is returned:
```javascript
...multiBuffer = function () {
var firstArgIndex = 0;
var commandName = _commandName;
if (commandName === null) {
commandName = arguments[0];

## Pipelining
If you want to send a batch of commands (e.g. > 5), you can use pipelining to queue
the commands in memory and then send them to Redis all at once. This way the performance improves by 50%~300% (See [benchmark section
](#benchmark)).
`redis.pipeline()` creates a `Pipeline` instance. You can call any Redis
commands on it just like the `Redis` instance. The commands are queued in memory
and flushed to Redis by calling the `exec` method:
```javascript
var pipeline = redis.pipeline();
pipeline.set('foo', 'bar');
pipeline.del('cc');

// Both `channel` and `message` are buffers.
});
```
`PSUBSCRIBE` is also supported in a similar way:
```javascript
redis.psubscribe('pat?ern', function (err, count) {});
redis.on('pmessage', function (pattern, channel, message) {});
redis.on('pmessageBuffer', function (pattern, channel, message) {});
```
When a client issues a SUBSCRIBE or PSUBSCRIBE, that connection is put into a "subscriber" mode.
At that point, only commands that modify the subscription set are valid.
When the subscription set is empty, the connection is put back into regular mode.

## Auto-reconnect
By default, ioredis will try to reconnect when the connection to Redis is lost
except when the connection is closed manually by `redis.disconnect()` or `redis.quit()`.
It's very flexible to control how long to wait to reconnect after disconnection
using the `retryStrategy` option:
```javascript
var redis = new Redis({
// This is the default value of `retryStrategy`
...quitBuffer = function () {
var firstArgIndex = 0;
var commandName = _commandName;
if (commandName === null) {
commandName = arguments[0];

of blocking the server for a long time. However, it requires recording the cursor on the client side each time
the `SCAN` command is called in order to iterate through all the keys correctly. Since it's a relatively common use case, ioredis
provides a streaming interface for the `SCAN` command to make things much easier. A readable stream can be created by calling `scanStream
`:
```javascript
var redis = new Redis();
// Create a readable stream (object mode)
var stream = redis.scanStream();
var keys = [];
stream.on('data', function (resultKeys) {
// `resultKeys` is an array of strings representing key names
for (var i = 0; i < resultKeys.length; i++) {
keys.push(resultKeys[i]);
}
});

`retryStrategy` is a function that will be called when the connection is lost.
The argument `times` means this is the nth reconnection being made and
the return value represents how long (in ms) to wait to reconnect. When the
return value isn't a number, ioredis will stop trying to reconnect, and the connection
will be lost forever if the user doesn't call `redis.connect()` manually.
When reconnected, the client will auto subscribe to channels that the previous connection subscribed to.
This behavior can be disabled by setting the `autoResubscribe` option to `false`.
And if the previous connection has some unfulfilled commands (most likely blocking commands such as `brpop` and `blpop`),
the client will resend them when reconnected. This behavior can be disabled by setting the `autoResendUnfulfilledCommands` option
to `false`.

`redis.pipeline()` creates a `Pipeline` instance. You can call any Redis
commands on it just like the `Redis` instance. The commands are queued in memory
and flushed to Redis by calling the `exec` method:
```javascript
var pipeline = redis.pipeline();
pipeline.set('foo', 'bar');
pipeline.del('cc');
pipeline.exec(function (err, results) {
// `err` is always null, and `results` is an array of responses
// corresponding to the sequence of queued commands.
// Each response follows the format `[err, result]`.
});
// You can even chain the commands:
...isEmpty = function () {
return this.channels('subscribe').length === 0 && this.channels('psubscribe').length === 0;
