NuCache Settings

This settings section allows you to specify the block size of the BTree used by NuCache. This is configured by default, so you don't need to configure this. However it is possible with something like:

"Umbraco": {
  "CMS": {
    "NuCache": {
      "BTreeBlockSize": 4096
    }
  }
}

This is how NuCache is configured by default. It is important to mention that the block size must be a power of two, at least 512, and at most 65536 (64K).

Additional Settings

It is possible to configure NuCache to work in memory only without reading/writing the NuCache database files.

For larger sites this is likely to increase startup duration for a "warm boot" however for a smaller site there should be little to no impact.

Unfortunately the settings have not yet been exposed via the new configuration setup, instead you must configure with a composer.

public class DisableNuCacheDatabaseComposer : IComposer
{
    public void Compose(IUmbracoBuilder builder)
    {
        var settings = new Umbraco.Cms.Infrastructure.PublishedCache.PublishedSnapshotServiceOptions
        {
            IgnoreLocalDb = true
        };
        builder.Services.AddSingleton(settings);
    }
}
