🚀 Quick start

public static RedisClient cli = new RedisClient("127.0.0.1:6379,password=123,defaultDatabase=13");
//cli.Serialize = obj => JsonConvert.SerializeObject(obj);
//cli.Deserialize = (json, type) => JsonConvert.DeserializeObject(json, type);
cli.Notice += (s, e) => Console.WriteLine(e.Log); //print command log

cli.Set("key1", "value1");
cli.MSet("key1", "value1", "key2", "value2");

string value1 = cli.Get("key1");
string[] vals = cli.MGet("key1", "key2");

Supports strings, hashes, lists, sets, sorted sets, bitmaps, hyperloglogs, geo, streams And BloomFilter.

Parameter	Default	Explain
protocol	RESP2	If you use RESP3, you need redis 6.0 environment
user	<empty>	Redis server username, requires redis-server 6.0
password	<empty>	Redis server password
defaultDatabase	0	Redis server database
max poolsize	100	Connection max pool size
min poolsize	5	Connection min pool size
idleTimeout	20000	Idle time of elements in the connection pool (MS), suitable for connecting to remote redis server
connectTimeout	10000	Connection timeout (MS)
receiveTimeout	10000	Receive timeout (MS)
sendTimeout	10000	Send timeout (MS)
encoding	utf-8	string charset
retry	0	Protocol error retry execution times
ssl	false	Enable encrypted transmission
name	<empty>	Connection name, use client list command to view
prefix	<empty>	The prefix of the key, all methods will have this prefix. cli.Set(prefix + "key", 111);

IPv6: [fe80::b164:55b3:4b4f:7ce6%15]:6379

🎣 Master-Slave

public static RedisClient cli = new RedisClient(
    "127.0.0.1:6379,password=123,defaultDatabase=13",
    "127.0.0.1:6380,password=123,defaultDatabase=13",
    "127.0.0.1:6381,password=123,defaultDatabase=13"
    );

var value = cli.Get("key1");

Write data at 127.0.0.1:6379; randomly read data from port 6380 or 6381.

⛳ Redis Sentinel

public static RedisClient cli = new RedisClient(
    "mymaster,password=123", 
    new [] { "192.169.1.10:26379", "192.169.1.11:26379", "192.169.1.12:26379" },
    true //This variable indicates whether to use the read-write separation mode.
    );

🌌 Redis Cluster

Suppose, a Redis cluster has three master nodes (7001-7003) and three slave nodes (7004-7006), then use the following code to connect to the cluster:

public static RedisClient cli = new RedisClient(
    new ConnectionStringBuilder[] { "192.168.0.2:7001", "192.168.0.2:7002", "192.168.0.2:7003" }
    );

⚡ Client-side-cahing

requires redis-server 6.0 and above

cli.UseClientSideCaching(new ClientSideCachingOptions
{
    //Client cache capacity
    Capacity = 3,
    //Filtering rules, which specify which keys can be cached locally
    KeyFilter = key => key.StartsWith("Interceptor"),
    //Check long-term unused cache
    CheckExpired = (key, dt) => DateTime.Now.Subtract(dt) > TimeSpan.FromSeconds(2)
});

📡 Subscribe

using (cli.Subscribe("abc", ondata)) //wait .Dispose()
{
    Console.ReadKey();
}

void ondata(string channel, string data) =>
    Console.WriteLine($"{channel} -> {data}");

📃 Scripting

var r1 = cli.Eval("return {KEYS[1],KEYS[2],ARGV[1],ARGV[2]}", 
    new[] { "key1", "key2" }, "first", "second") as object[];

var r2 = cli.Eval("return {1,2,{3,'Hello World!'}}") as object[];

cli.Eval("return redis.call('set',KEYS[1],'bar')", 
    new[] { Guid.NewGuid().ToString() })

💻 Pipeline

using (var pipe = cli.StartPipe())
{
    pipe.IncrBy("key1", 10);
    pipe.Set("key2", Null);
    pipe.Get("key1");

    object[] ret = pipe.EndPipe();
    Console.WriteLine(ret[0] + ", " + ret[2]);
}

📰 Transaction

using (var tran = cli.Multi())
{
    tran.IncrBy("key1", 10);
    tran.Set("key2", Null);
    tran.Get("key1");

    object[] ret = tran.Exec();
    Console.WriteLine(ret[0] + ", " + ret[2]);
}

📯 GetDatabase: switch database

using (var db = cli.GetDatabase(10))
{
    db.Set("key1", 10);
    var val1 = db.Get("key1");
}

🔍 Scan

Support cluster mode

foreach (var keys in cli.Scan("*", 10, null))
{
    Console.WriteLine(string.Join(", ", keys));
}
