Distributed MySQL Server Cache

The Distributed MySQL Server Cache implementation (AddDistributedMySqlCache) allows the distributed cache to use a MySQL Server database as its backing store. To create a MySQL Server cached item table in a MySQL Server instance, you can use the dotnet-mysql-cache tool. The tool creates a table with the name and schema that you specify.

Create a table in MySQL Server by running the dotnet mysql-cache create command. Provide the MySQL Server connection string, instance (for example server=192.169.0.1), table name (for example, NewTableName) and optional database (for example, MyDatabaseName):

dotnet mysql-cache create "server=192.169.0.1;user id=userName;password=P4ssword123!;port=3306;database=MyDatabaseName;Allow User Variables=True" "NewTableName" --databaseName "MyDatabaseName"

A message is logged to indicate that the tool was successful:

Table and index were created successfully.

The table created by the dotnet-mysql-cache tool has the following schema:

[!NOTE] An app should manipulate cache values using an instance of IDistributedCache, not any other.

The example snippet how to implement MySql Server cache in Program.cs:

builder.Services.AddDistributedMySqlCache(options =>
{
    options.ConnectionString = builder.Configuration.GetConnectionString("DistCache_ConnectionString");
    options.SchemaName = "MyDatabaseName";  //optional
    options.TableName = "NewTableName";     //required
});

[!NOTE] A ConnectionString (and optionally, SchemaName and TableName) are typically stored outside of source control (for example, stored by the Secret Manager or in appsettings.json/appsettings.{Environment}.json files). The connection string may contain credentials that should be kept out of source control systems.
