[Arkatufus]

1.5.28 September 9th 2024

• Bump Akka to 1.5.28
• Bump Akka.Hosting to v1.5.28
• Harden SQL journal and snapshot store against initialization failures
• Cleanup nullability warnings
• Port Akka.NET #7313: Made DateTime.UtcNow the default timestamp for SnapshotMetadata

Linq2Db DataOptions Support

You can now use DataOptions to set up your persistence journal, read journal, and snapshot store with a new Akka.Persistence.Sql.Hosting API.

Here is an example of setting up persistence on PostgreSQL using NpgsqlDataSource instead of the previous connection string and provider name setup.

var dataSource = new NpgsqlDataSourceBuilder(_myConnectionString).Build();

var dataOptions = new DataOptions()
    .UseDataProvider(DataConnection.GetDataProvider(ProviderName.PostgreSQL, dataSource.ConnectionString))
    .UseProvider(ProviderName.PostgreSQL)
    .UseConnectionFactory((opt) => dataSource.CreateConnection());
    
var host = new HostBuilder()
    .ConfigureServices((context, services) => {
        services.AddAkka("my-system-name", (builder, provider) =>
        {
            builder.WithSqlPersistence(dataOptions);
        });
    });
