Custom Grain Storage - Issues After Upgrading to Orleans 8 about orleans

[sec]

I see, maybe you can take a look ay my implementation as a reference, I've tested and it works under 8, until we get official docs.

Hi.
I hit the same issue, documentation and samples are not yet updated to 8.0, as you also saw :)

Based on your code, something like this should work:

    internal static IServiceCollection AddAzureShardedGrainStorage(
        this IServiceCollection services,
        string name,
        Action<OptionsBuilder<AzureShardedStorageOptions>> configureOptions = null)
    {
        configureOptions?.Invoke(services.AddOptions<AzureShardedStorageOptions>(name));

        services.ConfigureNamedOptionForLogging<AzureShardedStorageOptions>(name);

        return services.AddGrainStorage(name, AzureShardedGrainStorageFactory.Create);
    }

But I'm 100% sure if this is all that's needed after migrate to v8, because right know my custom provider it not working, method Participate is not called during Silo startup :(

edit: found out the issue, be sure to return your strong typed Storage class, not IGrainStorage as in the old example. Ex. public static AzureShardedGrainStorage Create(IServiceProvider services, string name)

Thanks @sec for the info. That would get past the build error, but wouldn't get it running (I did test to make sure). Hopefully the Orleans team might have some more info?

@ReubenBond - do you know how 'Custom Grain Storage' should be set up in Orleans 8 please? Are there any docs anywhere?

If there aren't any current docs and you can show me how to fix it, I could update/create the tutorial for Orleans 8. Here is an example of my standard of writing.

I've had a look at the above mentioned sample. I think it's missing a lot of new stuff.

I checked out the release notes, but couldn't see any pointers.

I checked out Orleans Contrib and found the Mongo provider, but I'm really struggling to work out the changes.

Does anyone from the Orleans team will know how to help please?

What do you miss exactly or maybe what problem are you facing? After those code changes and change in Storage factory return type, your provider should work - what errors are you getting?

[JsAndDotNet]

The same thing as you whereby Participate(ISiloLifecycle lifecycle) isn't called on the silo startup.

If you check out the Mongo Provider, it seems to be done in a very different manner in V8, but that provider is quite complex, so I'm having trouble working out exactly what's needed.

Did you get your repo working with the provider calling Participate?

[sec]

Yes, you need to change the return type in your storage factory to be like this

public static class AzureShardedGrainStorageFactory
{
    public static AzureShardedGrainStorage Create(IServiceProvider services, string name)
    {
        var options = services.GetRequiredService<IOptionsMonitor<AzureShardedStorageOptions>>().Get(name);
        return ActivatorUtilities.CreateInstance<AzureShardedGrainStorage>(services, options, name);
    }
}

I couldn't get it going, so I went to the Orleans repo and re-modelled my stuff based on the Redis provider.

Thanks for your help.

The tutorial is still out of date, so I'll leave this open as notification that the docs need updating. Appreciate the team have a lot on.

For anyone else who gets stuck, I now have the persistence provider working. Code can be found here.

It's based on the Redis provider, which is a nice example to follow.

I'm going to close this issue as my problem is resolved and hopefully others will be able to follow these examples.
