Cache manager

Common interface to manage cache using different providers.

How to install

Package Manager

Install-Package microservice.toolkit.cachemanager -Version 2.0.0

.NET CLI

dotnet add package microservice.toolkit.cachemanager --version 2.0.0

Package Reference

<PackageReference Include="microservice.toolkit.cachemanager" Version="2.0.0" />

ICacheManager interface

bool Set(string, TValue, long);

Task<bool> Set<TValue>(string key, TValue value)

bool Set<TValue>(string, TValue);

Task<bool> Set<TValue>(string key, TValue value, long issuedAt)

Adds an entry in the cache provider without expiration time.

TValue Get(string);

Task<TValue> Get<TValue>(string key)

Delete(string);

Task<bool> Delete(string key);

Removed the entry from the cache provider.

Implementations

• In-memory
• SqLite
• MySql
• Memcached
• Redis

In memory

<a name="inmemory"></a> Naif version of an in-memory cache implementation.

How to use:

var manager = new InMemoryCacheManager();

SQLite cache manager

<a name="sqlite"></a> To start using SQLite cache manager, first install the required package:

<PackageReference Include="Microsoft.Data.SQLite" Version="5.0.10" />

Create the table cache:

CREATE TABLE cache(
    id TEXT PRIMARY KEY,
    value TEXT NOT NULL,
    issuedAt INTEGER NOT NULL
);

And instantiate the cache manger:

var dbConnection = new SqliteConnection($"[CONNECTION_STRING]");
var manager = new SQLiteCacheManager(dbConnection);

You can specify value serializer, choose between "Newtonsoft JSON", "XML" and "System.Text.Json" (default).\

Newtonsoft JSON
Install Newtonsoft JSON dependency:

dotnet add package Newtonsoft.Json --version 13.0.2

And use the serializer:

var manager = new SQLiteCacheManager(dbConnection, new NewtonsoftJsonCacheValueSerializer());

System.Text.Json

var manager = new SQLiteCacheManager(dbConnection, new JsonCacheValueSerializer());

XML

var manager = new SQLiteCacheManager(dbConnection, new XmlCacheValueSerializer());

MySQL cache manager

<a name="mysql"></a> To start using MySql cache manager, first install the required package:

<PackageReference Include="MySqlConnector" Version="1.3.12" />

Create the table cache:

CREATE TABLE cache(
    id VARCHAR(256) PRIMARY KEY,
    value TEXT NOT NULL,
    issuedAt BIGINT NOT NULL
);

And instantiate the cache manger:

var dbConnection = new MySqlConnection($"[CONNECTION_STRING]");
var manager = new MysqlCacheManager(dbConnection);

You can specify value serializer, choose between "Newtonsoft JSON", "XML" and "System.Text.Json" (default).\

Newtonsoft JSON
Install Newtonsoft JSON dependency:

dotnet add package Newtonsoft.Json --version 13.0.2

And use the serializer:

var manager = new MysqlCacheManager(dbConnection, new NewtonsoftJsonCacheValueSerializer());

System.Text.Json

var manager = new MysqlCacheManager(dbConnection, new JsonCacheValueSerializer());

XML

var manager = new MysqlCacheManager(dbConnection, new XmlCacheValueSerializer());

Memcached

<a name="memcached"></a> To start using Memcached cache manager, first install the required package:

<PackageReference Include="Enyim.Memcached2" Version="0.6.8" />

How to use:

var manager = new MemcachedCacheManager("localhost:11211");

Or, if you are using a cluster:

var manager = new MemcachedCacheManager("localhost:11211,localhost:11212");

Redis

<a name="redis"></a> To start using Redis cache manager, first install the required package:

<PackageReference Include="StackExchange.Redis" Version="2.2.62" />

How to use:

var manager = new RedisCacheManager("localhost:6379");

You can specify value serializer, choose between "Newtonsoft JSON", "XML" and "System.Text.Json" (default).\

Newtonsoft JSON
Install Newtonsoft JSON dependency:

dotnet add package Newtonsoft.Json --version 13.0.2

And use the serializer:

var manager = new RedisCacheManager("localhost:6379", new NewtonsoftJsonCacheValueSerializer());

System.Text.Json

var manager = new RedisCacheManager("localhost:6379", new JsonCacheValueSerializer());

XML

var manager = new RedisCacheManager("localhost:6379", new XmlCacheValueSerializer());
