6 months ago Hi @suchoss , and thanks for considering FusionCache!
It's probably not the best choice, since the memory cache gives you some features that a distributed alone would not.
Having said that, while you cannot totally remove the 1st level (memory), what you can do is you can skip the memory cache, either on the read phase, on the write phase or both.
A nice thing for most of the options in FusionCache is that you can tweak them granularly, on a call-by-call basis, and the options you are looking for is called SkipMemoryCache, and you can specify it like this:
// GET OR SET
cache.GetOrSet<Product>(
$"product:{id}",
_ => GetProductFromDb(id),
options => options.SetSkipMemoryCache(true)
);
// SET
cache.Set<Product>(
$"product:{id}",
myProduct,
options => options.SetSkipMemoryCache(true)
);If you want to avoid having to specify SetSkipMemoryCache(true) for every call, you can of course set that in the DefaultEntryOptions that will be used both as a default for when in each specific call you will not specify any options at all, or as a "starting point" for when you'll use the options => options.Whatever(...) version.
If I may though, I'd like to suggest a different path: you can also specify a different Duration for the distributed level, so that you can cache the values there for more time and for a very low amount of time in the memory cache.
In this way you'll have the memory cache automatically populated with the most used values, and the less used will only be in the distributed cache, saving you memory on the client side.
Hope this helps!
Let me know if this worked so i can close this issue.

Is it possible to skip saving data to InMemory and use only 2nd level distributed cache?
We have some really heavy distributed cache with more than 5 GB of data and also some small caches up to 10 MB.
I can imagine that those small ones would be in memory or in memory with 2nd level support. But the big heavy cache would be only in distributed cache.
Thanks
