    Advice on implementing a caching strategy in Umbraco:

    Hello everyone I'm an Umbraco Newbie and I'm trying to implement cache on my website.

    Let's say we have a website that specialize in cook recipes. We have hundreds of recipes, better: ~1000 recipes.

    My Umbraco Backoffice looks something like this:

        Avocado Breakfast Bowl
        more recipes starting with a A
        Bar-B-Que Sauce
        more recipes starting with a B
        Za'atar chicken thigs
        more recipes starting with a Z

    Every page of our website is made of cook recipes filtered in different ways:

    featured cook recipes 
    last cook recipes
    most voted cook recipes
    and so on.

    The strategy I'm using at the moment is really basic: I'm using @html.CachedPartial wherever I can (15 seconds caching =>

    But since every 10 seconds I need to:

    • Get all the descendants of the Recipes Tree (for later filtering by the various @html.CachedPartial).
    • Rebuild a dropdown with all the cooks that have a recipe published on the site.

    And these objects are used all over the application I would like to leverage the Umbraco Cache to:

    • Cache an object with all the IPublishedContent Recipes
    • Cache an object with all the cooks (as I need to search in every recipe for the cook name so that I can show only cooks that have published recipes) And bust the cache on a backoffice publish event.

    Is this possible? Is this a good idea?

    In the 2016 talk "pushing umbraco to the limit": @11:30 ~ 14:15

    they talk about implementing a custom CacheRefresher so I guess it can be done. bonus: this should work also in a load balanced application.

    Here is the official doc: but it's a bit cryptic for me.

    p.s.: In the last days I've read a lot about caching in both Umbraco and .Net and I've amassed a lot of information, as soon as I reorganize it I'm going to add it to this post for future reference.
