memento.caffeine — org.clojars.roklenarcic/memento 1.1.42

Caffeine cache implementation.

assoc-imm-val! clj

(assoc-imm-val! transient-m k v xf)

If cached value is a completable future with immediately available value, assoc it to transient.

conf->builder clj

(conf->builder {:memento.core/keys [initial-capacity size< ttl fade]
                :memento.caffeine/keys [weight< removal-listener kv-weight
                                        weak-keys weak-values soft-values
                                        refresh stats ticker]}
               sec-index)

Creates and configures common parameters on the builder.

conf->sec-index clj

(conf->sec-index {:memento.core/keys [concurrency initial-capacity]})

Creates secondary index for evictions

load-data clj

(load-data cache data-map)

stats clj

(stats fn-or-cache)

Return caffeine stats for the cache if it is a caffeine Cache.

Takes a memoized fn or a Cache instance as a parameter.

Returns com.github.benmanes.caffeine.cache.stats.CacheStats

to-data clj

(to-data {:keys [caffeine-cache] :as _cache})

val->cval clj

(val->cval v)

Converts val into cache friendly version. The problem is that AsyncCache has 'smart' feature where it will delete entries where CompletableFuture has nil value or exception value.
