Hello! I have a question about pathom2's cache. I have a resolver that returns a vector of items. How can I associate those items with an ident so that I don’t have to look them up again if they’ve already been returned? The basic code looks like:

(pc/defresolver items-resolver
  [_]
  {::items [{::item {::id 0 ::name "foo" ::depends-on nil}}
            {::item {::id 1 ::name "bar" ::depends-on {::id 0}}}]})

(pc/defresolver item-resolver
  [{id ::id}]
  ;; Don't want this to have to be called for the `depends-on` key in my query below
  {::item (get-from-db)})

(pc/defresolver item-normalizer
  [{item ::item}]
  {::id ...
   ::name ...
   ::depends-on ...})

;; Query
[{::items [::name {::depends-on [::name]}]}]

;; Expected result
{::items [{::name "foo" ::depends-on nil}
          {::name "bar" ::depends-on {::name "foo"}}]}

Pathom doesn't have the concept of normalization like that

one thing you can do is manually pre-fill the cache for a resolver you expect is going to be called

the batch works like this too, you have to add a cache entry on the resolver with the exact input and output you want (the input must have only the keys required by the resolver, otherwise the cache will miss)

this line has an example of pathom caching: https://github.com/wilkerlucio/pathom/blob/master/src/com/wsscode/pathom/connect.cljc#L837
