C#/.NET Client for Redis

Redis Connection Strings

Redis Connection strings have been expanded to support the more versatile URI format which is now able to capture most of Redis Client settings in a single connection string (akin to DB Connection strings).

Redis Connection Strings supports multiple URI-like formats, from a simple hostname or IP Address and port pair to a fully-qualified URI with multiple options specified on the QueryString.

Some examples of supported formats:

localhost
127.0.0.1:6379
redis://localhost:6379
password@localhost:6379
clientid:password@localhost:6379
redis://clientid:password@localhost:6380?ssl=true&db=1

More examples can be seen in ConfigTests.cs

Any additional configuration can be specified as QueryString parameters. The full list of options that can be specified include:

Ssl	bool	If this is an SSL connection
Db	int	The Redis DB this connection should be set to
Client	string	A text alias to specify for this connection for analytic purposes
Password	string	UrlEncoded version of the Password for this connection
ConnectTimeout	int	Timeout in ms for making a TCP Socket connection
SendTimeout	int	Timeout in ms for making a synchronous TCP Socket Send
ReceiveTimeout	int	Timeout in ms for waiting for a synchronous TCP Socket Receive
IdleTimeOutSecs	int	Timeout in Seconds for an Idle connection to be considered active
NamespacePrefix	string	Use a custom prefix for ServiceStack.Redis internal index colletions

Redis Client Managers

The recommended way to access RedisClient instances is to use one of the available Thread-Safe Client Managers below. Client Managers are connection factories which is ideally registered as a Singleton either in your IOC or static classes.

RedisManagerPool

With the enhanced Redis URI Connection Strings we've been able to simplify and streamline the existing PooledRedisClientManager implementation and have extracted it out into a new clients manager called RedisManagerPool.

In addition to removing all above options on the Client Manager itself, readonly connection strings have also been removed so the configuration ends up much simpler and more aligned with the common use-case:

container.Register<IRedisClientsManager>(c => 
    new RedisManagerPool(redisConnectionString));

Pooling Behavior

Any connections required after the maximum Pool size has been reached will be created and disposed outside of the Pool. By not being restricted to a maximum pool size, the pooling behavior in RedisManagerPool can maintain a smaller connection pool size at the cost of potentially having a higher opened/closed connection count.

PooledRedisClientManager

If you prefer to define options on the Client Manager itself or you want to provide separate Read/Write and ReadOnly (i.e. Master and Slave) redis-servers, use the PooledRedisClientManager instead:

container.Register<IRedisClientsManager>(c => 
    new PooledRedisClientManager(redisReadWriteHosts, redisReadOnlyHosts) { 
        ConnectTimeout = 100,
        //...
    });

Pooling Behavior

The PooledRedisClientManager imposes a maximum connection limit and when its maximum pool size has been reached will instead block on any new connection requests until the next RedisClient is released back into the pool. If no client became available within PoolTimeout, a Pool TimeoutException will be thrown.

BasicRedisClientManager

If don't want to use connection pooling (i.e. your accessing a local redis-server instance) you can use a basic (non-pooled) Clients Manager which creates a new RedisClient instance each time:

container.Register<IRedisClientsManager>(c => 
    new BasicRedisClientManager(redisConnectionString));

Accessing the Redis Client

Once registered, accessing the RedisClient is the same in all Client Managers, e.g:

var clientsManager = container.Resolve<IRedisClientsManager>();
using (IRedisClient redis = clientsManager.GetClient())
{
    redis.IncrementValue("counter");
    List<string> days = redis.GetAllItemsFromList("days");

    //Access Typed API
    var redisTodos = redis.As<Todo>();

    redisTodos.Store(new Todo {
        Id = redisTodos.GetNextSequence(),
        Content = "Learn Redis",
    });

    var todo = redisTodos.GetById(1);

    //Access Native Client
    var redisNative = (IRedisNativeClient)redis;

    redisNative.Incr("counter");
    List<string> days = redisNative.LRange("days", 0, -1);
}

A more detailed list of the available RedisClient API's used in the example can be seen in the C# interfaces below:

ServiceStack.Redis SSL Support

ServiceStack.Redis now supporting SSL connections making it suitable for accessing remote Redis server instances over a secure SSL connection.

Connecting to Azure Redis

As connecting to Azure Redis Cache via SSL was the primary use-case for this feature, we've added a new Getting connected to Azure Redis via SSL to help you get started.

New Generic API's for calling Custom Redis commands

Most of the time when waiting to use a new Redis Command you'll need to wait for an updated version of ServiceStack.Redis to add support for the new commands likewise there are times when the Redis Client doesn't offer every permutation that redis-server supports.

With the new Custom and RawCommand API's on IRedisClient and IRedisNativeClient you can now use the RedisClient to send your own custom commands that can call adhoc Redis commands:

public interface IRedisClient
{
    ...
    RedisText Custom(params object[] cmdWithArgs);
}

public interface IRedisNativeClient
{
    ...
    RedisData RawCommand(params object[] cmdWithArgs);
    RedisData RawCommand(params byte[][] cmdWithBinaryArgs);
}

These Custom API's take a flexible object[] arguments which accepts any serializable value e.g. byte[], string, int as well as any user-defined Complex Types which are transparently serialized as JSON and send across the wire as UTF-8 bytes.

var ret = Redis.Custom("SET", "foo", 1);          // ret.Text = "OK"

byte[] cmdSet = Commands.Set;
ret = Redis.Custom(cmdSet, "bar", "b");           // ret.Text = "OK"

ret = Redis.Custom("GET", "foo");                 // ret.Text = "1"

There are also convenient extension methods on RedisData and RedisText that make it easy to access structured data, e.g:

var ret = Redis.Custom(Commands.Keys, "*");
var keys = ret.GetResults();                      // keys = ["foo", "bar"]

ret = Redis.Custom(Commands.MGet, "foo", "bar");
var values = ret.GetResults();                    // values = ["1", "b"]

Enum.GetNames(typeof(DayOfWeek)).ToList()
    .ForEach(x => Redis.Custom(Commands.RPush, "DaysOfWeek", x));
ret = Redis.Custom(Commands.LRange, "DaysOfWeek", 1, -2);
var weekDays = ret.GetResults();      

weekDays.PrintDump(); // ["Monday", "Tuesday", "Wednesday", "Thursday", "Friday"]

and some more examples using Complex Types with the Custom API's:

var ret = Redis.Custom(Commands.Set, "foo", new Poco { Name = "Bar" }); // ret.Text = "OK"

ret = Redis.Custom(Commands.Get, "foo");          // ret.Text =  {"Name":"Bar"}
Poco dto = ret.GetResult<Poco>();

dto.Name.Print(); // Bar

New Managed Pub/Sub Server

The Pub/Sub engine powering Redis ServerEvents and Redis MQ has been extracted and encapsulated it into a re-usable class that can be used independently for handling messages published to specific Redis Pub/Sub channels.

RedisPubSubServer processes messages in a managed background thread that automatically reconnects when the redis-server connection fails and works like an independent background Service that can be stopped and started on command.

The public API is captured in the IRedisPubSubServer interface:

public interface IRedisPubSubServer : IDisposable
{
    IRedisClientsManager ClientsManager { get; }
    // What Channels it's subscribed to
    string[] Channels { get; }

    // Run once on initial StartUp
    Action OnInit { get; set; }
    // Called each time a new Connection is Started
    Action OnStart { get; set; }
    // Invoked when Connection is broken or Stopped
    Action OnStop { get; set; }
    // Invoked after Dispose()
    Action OnDispose { get; set; }

    // Fired when each message is received
    Action<string, string> OnMessage { get; set; }
    // Fired after successfully subscribing to the specified channels
    Action<string> OnUnSubscribe { get; set; }
    // Called when an exception occurs 
    Action<Exception> OnError { get; set; }
    // Called before attempting to Failover to a new redis master
    Action<IRedisPubSubServer> OnFailover { get; set; }

    int? KeepAliveRetryAfterMs { get; set; }
    // The Current Time for RedisServer
    DateTime CurrentServerTime { get; }

    // Current Status: Starting, Started, Stopping, Stopped, Disposed
    string GetStatus();
    // Different life-cycle stats
    string GetStatsDescription();
    
    // Subscribe to specified Channels and listening for new messages
    IRedisPubSubServer Start();
    // Close active Connection and stop running background thread
    void Stop();
    // Stop than Start
    void Restart();
}

Usage

To use RedisPubSubServer, initialize it with the channels you want to subscribe to and assign handlers for each of the events you want to handle. At a minimum you'll want to handle OnMessage:

var clientsManager = new PooledRedisClientManager();
var redisPubSub = new RedisPubSubServer(clientsManager, "channel-1", "channel-2") {
        OnMessage = (channel, msg) => "Received '{0}' from '{1}'".Print(msg, channel)
    }.Start();

Calling Start() after it's initialized will get it to start listening and processing any messages published to the subscribed channels.

New Lex Operations

The new ZRANGEBYLEX sorted set operations allowing you to query a sorted set lexically have been added. A good showcase for this is available on autocomplete.redis.io.

These new operations are available as a 1:1 mapping with redis-server on IRedisNativeClient:

public interface IRedisNativeClient
{
    ...
    byte[][] ZRangeByLex(string setId, string min, string max, int? skip=null, int? take=null);
    long ZLexCount(string setId, string min, string max);
    long ZRemRangeByLex(string setId, string min, string max);
}

And the more user-friendly APIs under IRedisClient:

public interface IRedisClient
{
    ...
    List<string> SearchSortedSet(string setId, string start=null, string end=null);
    long SearchSortedSetCount(string setId, string start=null, string end=null);
    long RemoveRangeFromSortedSetBySearch(string setId, string start=null, string end=null);
}

Just like NuGet version matchers, Redis uses [ char to express inclusiveness and ( char for exclusiveness. Since the IRedisClient APIs defaults to inclusive searches, these two APIs are the same:

Redis.SearchSortedSetCount("zset", "a", "c")
Redis.SearchSortedSetCount("zset", "[a", "[c")

Alternatively you can specify one or both bounds to be exclusive by using the ( prefix, e.g:

Redis.SearchSortedSetCount("zset", "a", "(c")
Redis.SearchSortedSetCount("zset", "(a", "(c")

More API examples are available in LexTests.cs.

New HyperLog API

The development branch of Redis server (available when v3.0 is released) includes an ingenious algorithm to approximate the unique elements in a set with maximum space and time efficiency. For details about how it works see Redis's creator Salvatore's blog who explains it in great detail. Essentially it lets you maintain an efficient way to count and merge unique elements in a set without having to store its elements. A Simple example of it in action:

redis.AddToHyperLog("set1", "a", "b", "c");
redis.AddToHyperLog("set1", "c", "d");
var count = redis.CountHyperLog("set1"); //4

redis.AddToHyperLog("set2", "c", "d", "e", "f");

redis.MergeHyperLogs("mergedset", "set1", "set2");

var mergeCount = redis.CountHyperLog("mergedset"); //6

New Scan APIs Added

Redis v2.8 introduced a beautiful new SCAN operation that provides an optimal strategy for traversing a redis instance entire keyset in managable-size chunks utilizing only a client-side cursor and without introducing any server state. It's a higher performance alternative and should be used instead of KEYS in application code. SCAN and its related operations for traversing members of Sets, Sorted Sets and Hashes are now available in the Redis Client in the following API's:

public interface IRedisClient
{
    ...
    IEnumerable<string> ScanAllKeys(string pattern = null, int pageSize = 1000);
    IEnumerable<string> ScanAllSetItems(string setId, string pattern = null, int pageSize = 1000);
    IEnumerable<KeyValuePair<string, double>> ScanAllSortedSetItems(string setId, string pattern = null, int pageSize = 1000);
    IEnumerable<KeyValuePair<string, string>> ScanAllHashEntries(string hashId, string pattern = null, int pageSize = 1000);    
}

//Low-level API
public interface IRedisNativeClient
{
    ...
    ScanResult Scan(ulong cursor, int count = 10, string match = null);
    ScanResult SScan(string setId, ulong cursor, int count = 10, string match = null);
    ScanResult ZScan(string setId, ulong cursor, int count = 10, string match = null);
    ScanResult HScan(string hashId, ulong cursor, int count = 10, string match = null);
}

The IRedisClient provides a higher-level API that abstracts away the client cursor to expose a lazy Enumerable sequence to provide an optimal way to stream scanned results that integrates nicely with LINQ, e.g:

var scanUsers = Redis.ScanAllKeys("urn:User:*");
var sampleUsers = scanUsers.Take(10000).ToList(); //Stop after retrieving 10000 user keys

New IRedisClient LUA API's

The IRedisClient API's for redis server-side LUA support have been re-factored into the more user-friendly API's below:

public interface IRedisClient 
{
    //Eval/Lua operations 

    string ExecLuaAsString(string luaBody, params string[] args);
    string ExecLuaAsString(string luaBody, string[] keys, string[] args);
    string ExecLuaShaAsString(string sha1, params string[] args);
    string ExecLuaShaAsString(string sha1, string[] keys, string[] args);
    
    int ExecLuaAsInt(string luaBody, params string[] args);
    int ExecLuaAsInt(string luaBody, string[] keys, string[] args);
    int ExecLuaShaAsInt(string sha1, params string[] args);
    int ExecLuaShaAsInt(string sha1, string[] keys, string[] args);

    List<string> ExecLuaAsList(string luaBody, params string[] args);
    List<string> ExecLuaAsList(string luaBody, string[] keys, string[] args);
    List<string> ExecLuaShaAsList(string sha1, params string[] args);
    List<string> ExecLuaShaAsList(string sha1, string[] keys, string[] args);

    string CalculateSha1(string luaBody);
    
    bool HasLuaScript(string sha1Ref);
    Dictionary<string, bool> WhichLuaScriptsExists(params string[] sha1Refs);
    void RemoveAllLuaScripts();
    void KillRunningLuaScript();
    string LoadLuaScript(string body);
}

Usage Examples

Here's how you can implement a ZPOP in Lua to remove the items with the lowest rank from a sorted set:

var luaBody = @"
    local val = redis.call('zrange', KEYS[1], 0, ARGV[1]-1)
    if val then redis.call('zremrangebyrank', KEYS[1], 0, ARGV[1]-1) end
    return val";

var i = 0;
var alphabet = 26.Times(c => ((char)('A' + c)).ToString());
alphabet.ForEach(x => Redis.AddItemToSortedSet("zalphabet", x, i++));

//Remove the letters with the lowest rank from the sorted set 'zalphabet'
var letters = Redis.ExecLuaAsList(luaBody, keys: new[] { "zalphabet" }, args: new[] { "3" });
letters.PrintDump(); //[A, B, C]

And how to implement ZREVPOP to remove items with the highest rank from a sorted set:

var luaBody = @"
    local val = redis.call('zrange', KEYS[1], -ARGV[1], -1)
    if val then redis.call('zremrangebyrank', KEYS[1], -ARGV[1], -1) end
    return val";

var i = 0;
var alphabet = 26.Times(c => ((char)('A' + c)).ToString());
alphabet.ForEach(x => Redis.AddItemToSortedSet("zalphabet", x, i++));

//Remove the letters with the highest rank from the sorted set 'zalphabet'
List<string> letters = Redis.ExecLuaAsList(luaBody, keys: new[] { "zalphabet" }, args: new[] { "3" });

letters.PrintDump(); //[X, Y, Z]

Other examples

Returning an int:

int intVal = Redis.ExecLuaAsInt("return 123"); //123
int intVal = Redis.ExecLuaAsInt("return ARGV[1] + ARGV[2]", "10", "20"); //30

Returning an string:

var strVal = Redis.ExecLuaAsString(@"return 'Hello, ' .. ARGV[1] .. '!'", "Redis Lua"); //Hello, Redis Lua!

Returning a List of strings:

Enum.GetNames(typeof(DayOfWeek)).ToList()
    .ForEach(x => Redis.AddItemToList("DaysOfWeek", x));

var daysOfWeek = Redis.ExecLuaAsList("return redis.call('LRANGE', 'DaysOfWeek', 0, -1)");
daysOfWeek.PrintDump(); //[Sunday, Monday, Tuesday, ...]

More examples can be found in the Redis Eval Lua tests

Overview

The Redis client is an independent project and can be used with or without the ServiceStack webservices framework.

Redis is one of the fastest and most feature-rich key-value stores to come from the NoSQL movement. It is similar to memcached but the dataset is not volatile, and values can either be strings lists, sets, sorted sets or hashes.

ServiceStack's C# Redis Client is an Open Source C# Redis client based on Miguel de Icaza previous efforts with redis-sharp.

There are a number of different APIs available which are all a friendly drop-in with your local IOC: The ServiceStack.Redis.RedisClient class below implements the following interfaces:

ICacheClient - If you are using Redis solely as a cache, you should bind to the ServiceStack's common interface as there already are In-Memory an Memcached implementations available in ServiceStack, allowing you to easily switch providers in-future.
IRedisNativeClient - For those wanting a low-level raw byte access (where you can control your own serialization/deserialization) that map 1:1 with Redis operations of the same name.

For most cases if you require access to Redis-specific functionality you would want to bind to the interface below:

IRedisClient - Provides a friendlier, more descriptive API that lets you store values as strings (UTF8 encoding).
IRedisTypedClient - created with IRedisClient.As<T>() - it returns a 'strongly-typed client' that provides a typed-interface for all redis value operations that works against any C#/.NET POCO type.

The class hierachy for the C# Redis clients effectively look like:

RedisTypedClient (POCO) > RedisClient (string) > RedisNativeClient (raw byte[])

Each client provides a different layer of abstraction:

The RedisNativeClient exposes raw byte[] apis and does no marshalling and passes all values directly to redis.
The RedisClient assumes string values and simply converts strings to UTF8 bytes before sending to Redis
The RedisTypedClient provides a generic interface allowing you to add POCO values. The POCO types are serialized using .NETs fastest JSON Serializer which is then converted to UTF8 bytes and sent to Redis.

Redis Client API Overview

Thread-safe client managers

For multi-threaded applications you can choose from our different client connection managers:

BasicRedisClientManager - a load-balance (master-write and read-slaves) client manager that returns a new IRedisClient connection with the defaults specified (faster when accessing a redis-server instance on the same host).
PooledRedisClientManager - a load-balanced (master-write and read-slaves) client manager that utilizes a pool of redis client connections (faster when accessing a redis-server instance over the network).

Simple example using Redis Lists

Below is a simple example to give you a flavour of how easy it is to use some of Redis's advanced data structures - in this case Redis Lists: Full source code of this example is viewable online

{
    //Create a 'strongly-typed' API that makes all Redis Value operations to apply against Shippers

Speed

One of the best things about Redis is the speed - it is quick.

This example below stores and gets the entire Northwind database (3202 records) in less 1.2 secs - we've never had it so quick!

(Running inside a VS.NET/R# unit test on a 3 year old iMac)

using (var client = new RedisClient())
{
    var before = DateTime.Now;
    client.StoreAll(NorthwindData.Categories);
    client.StoreAll(NorthwindData.Customers);
    client.StoreAll(NorthwindData.Employees);
    client.StoreAll(NorthwindData.Shippers);
    client.StoreAll(NorthwindData.Orders);
    client.StoreAll(NorthwindData.Products);
    client.StoreAll(NorthwindData.OrderDetails);
    client.StoreAll(NorthwindData.CustomerCustomerDemos);
    client.StoreAll(NorthwindData.Regions);
    client.StoreAll(NorthwindData.Territories);
    client.StoreAll(NorthwindData.EmployeeTerritories);

    Console.WriteLine("Took {0}ms to store the entire Northwind database ({1} records)",
        (DateTime.Now - before).TotalMilliseconds, totalRecords);


    before = DateTime.Now;
