Dynamic Cache Key in GetOrSetAsync Factory

[ShaumCAtCpdi]

Hello!

I was wondering is there a way to change the CacheKey that will be set as part of the factory of GetOrSetAsync? I can do it outside of the factory but I was more curious if there was a way to do so within the factory with the ctx object

Example is this:

public async Task<Result<ObjectDto>> GetObjectByIdentifier(string objectIdentifier, CancellationToken cts = default)
{
	return await _cache.GetOrSetAsync<Result<ObjectDto>>(
		CacheKeys.Object.ByObjectIdentifier(objectIdentifier),
		async (ctx, ct) =>
		{
            // Call Repository Method
			var objectResult = await _objectRepository.GetObjectByIdentifier(objectIdentifier, ct);
			
            // Check if Repository Method is a Success
            if (!object.Success)
                return ctx.Fail(objectResult.ErrorCode);

            // Change the cache key here to be By ObjectId instead of ObjectIdentifier
            // i.e. CacheKeys.Object.ByObjectId(objectResult.Id)

            // Return Result
			return objectResult;
		},
		tags: [CacheKeys.Object.Tag],
		failSafeDefaultValue: Result<ObjectDto>.Fail(ErrorMessages.Codes.Server.InternalError),
		token: cts
	);
}

Hi @ShaumCAtCpdi
no, there's no way to do it: the cache key is the fundamental piece of information that uniquely identify each entry in the cache, and computing it (or changing it) mid-flight cannot possibly work.

Hope this helps.

Ok I figured as much! Perfect thank you so much for your response and thank you for making such an amazing tool with incredible documentation. I just became the Lead Developer and Architect for my Company and have been implementing lots of standards and actually getting to implement caching with such robust tools and explanations has been a ton of fun and a great joy! Looking forward to all the new things to come!
