MySQL

MySQL is an open-source relational database management system. CAP has supported MySQL as persistent.

Configuration

To use MySQL storage, you need to install the following extensions from NuGet:

PM> Install-Package DotNetCore.CAP.MySql

Next, add configuration items to the ConfigureServices method of Startup.cs.

public void ConfigureServices(IServiceCollection services)
{
    // ...

    services.AddCap(x =>
    {
        x.UseMySql(opt=>{
            //MySqlOptions
        });
        // x.UseXXX ...
    });
}

ADO.NET with transaction

private readonly ICapPublisher _capBus;

using (var connection = new MySqlConnection(AppDbContext.ConnectionString))
{
    using (var transaction = connection.BeginTransaction(_capBus, autoCommit: false))
    {
        //your business code
        connection.Execute("insert into test(name) values('test')", 
            transaction: (IDbTransaction)transaction.DbTransaction);

        _capBus.Publish("sample.rabbitmq.mysql", DateTime.Now);

        transaction.Commit();
    }
}

EntityFramework with transaction

private readonly ICapPublisher _capBus;

using (var trans = dbContext.Database.BeginTransaction(_capBus, autoCommit: false))
{
    dbContext.Persons.Add(new Person() { Name = "ef.transaction" });

    _capBus.Publish("sample.rabbitmq.mysql", DateTime.Now);

    dbContext.SaveChanges();
    trans.Commit();
