Invalidation cache

Cache invalidation

You can invalidate cache entries by tags defined in tag templates.

Automatic by endpoints

{
    "Key": "deleteProduct",
    "UpstreamHttpMethod": [ "Delete" ],
    "DownstreamPathTemplate": "/api/producsts/{id}",
    "UpstreamPathTemplate": "/products/{id}",
    "InvalidateCache": ["product:{tenantId}", "product:{tenantId}:{id}"], // 👈 Invalidate cache by tags
}

Manual

public class ProductsService {
    private readonly IOutputCacheStore _outputCacheStore;

    public ProductsService(IOutputCacheStore outputCacheStore)
    {
        _outputCacheStore = outputCacheStore;
    }

    public async Task DeleteProduct(int tenantId, int id)
    {
        // 👇 Invalidate cache by tags
        await _outputCacheStore.InvalidateAsync($"product:{tenantId}", $"product:{tenantId}:{id}");
        // ...
    }
}

Nebolo by lepšie nazvať to InvalidateCacheTags?

[Burgyn]

Ja som nad tým tiež rozmýšľal. Ale povedal som si, že to tam nedám lebo invalidacia podľa tagov je vlastne štandard v tomto type kešovanie, takže by to tam za mňa bola zbytočná informácia.
