CloudStructures

CloudStructures is the Redis client based on StackExchange.Redis.

StackExchange.Redis is very pure and low level library. It's Redis driver like ADO.NET. It's difficult to use it as raw. CloudStructures provides simple O/R (Object / Redis) mapper like Dapper for ADO.NET.

Support framework

• .NET 6+
• .NET Standard 2.0+
• .NET Framework 4.6.1+

Installation

dotnet add package CloudStructures

Data structures of Redis

CloudStructures supports these Redis data types. All methods are async.

Structure	Description
RedisBit	Bits API
RedisDictionary<TKey, TValue>	Hashes API with constrained value type
RedisGeo<T>	Geometries API
RedisHashSet<T>	like RedisDictionary<T, bool>
RedisHyperLogLog<T>	HyperLogLogs API
RedisList<T>	Lists API
RedisLua	Lua eval API
RedisSet<T>	Sets API
RedisSortedSet<T>	SortedSets API
RedisString<T>	Strings API

Getting started

Following code is simple sample.

// RedisConnection have to be held as static.
public static class RedisServer
{
    public static RedisConnection Connection { get; }
    public static RedisServer()
    {
        var config = new RedisConfig("name", "connectionString");
        Connection = new RedisConnection(config);
    }
}

// A certain data class
public class Person
{
    public string Name { get; set; }
    public int Age { get; set; }
}

// 1. Create redis structure
var key = "test-key";
var defaultExpiry = TimeSpan.FromDays(1);
var redis = new RedisString<Person>(RedisServer.Connection, key, defaultExpiry)

// 2. Call command
var neuecc = new Person("neuecc", 35);
await redis.SetAsync(neuecc);
var result = await redis.GetAsync();

ValueConverter

If you use this library, you should implement IValueConverter to serialize your original class. Unless you pass custom IValueConverter to RedisConnection ctor, fallback to SystemTextJsonConverter automatically that is default converter we provide.

How to implement custom IValueConverter

using CloudStructures.Converters;
using Utf8Json;
using Utf8Json.Resolvers;

namespace HowToImplement_CustomValueConverter
{
    public sealed class Utf8JsonConverter : IValueConverter
    {
        public byte[] Serialize<T>(T value)
            => JsonSerializer.Serialize(value, StandardResolver.AllowPrivate);

        public T Deserialize<T>(byte[] value)
            => JsonSerializer.Deserialize<T>(value, StandardResolver.AllowPrivate);
    }
}

using CloudStructures.Converters;
using MessagePack;
using MessagePack.Resolvers;

namespace HowToImplement_CustomValueConverter
{
    public sealed class MessagePackConverter : IValueConverter
    {
        private MessagePackSerializerOptions Options { get; }

        public MessagePackConverter(MessagePackSerializerOptions options)
            => this.Options = options;

        public byte[] Serialize<T>(T value)
            => MessagePackSerializer.Serialize(value, this.Options);

        public T Deserialize<T>(byte[] value)
            => MessagePackSerializer.Deserialize<T>(value, this.Options);
    }
}
