Re: Understanding clojure.core.cache TTL cache

I see. But I didn't really grasp the whole concept firmly . c3 holds a map containing {:a 1} that will lives for two minutes. After two minutes, requesting :a is generating false since it reached its TTL but it will still live in map until it is removed explicitly by invoking evict. Correct? Als

Understanding clojure.core.cache TTL cache

Hi, I created this: (def c3 (cache/ttl-cache-factory {:a 1} :ttl 2)) user=> c3 {:a 1} user=> (cache/has? c3 :a) true user=> (cache/has? c3 :a) false user=> c3 {:a 1} user=> (cache/evict c3 :a) {} user=> c3 {:a 1} After TTL, cache doesn't has :a entry but printing the var shows the map conta

Better ideas how to collect analytics data

Hi, I'm collecting analytics data. I used a master map that holds many other nested maps. Considering maps are immutable, many new maps are going to be allocated. (Yes, that is efficient in Clojure). Basic operation that I'm using is update-in , very convenient. Do you have a better idea how to c

Hi, I have a ref type that wraps a map, this map is going to embed many nested other maps. According to immutability rules, what happens when: A new nested map is updated (entry is removed or update) or even a new nested map is added to the master map that is wrapped by ref type? Thanks for help
