redimize

A Clojure library that provides two level caching to core.memoize then redis on cache miss

Usage

Expire is in seconds if no value passed it defaults to 1 hour, passing -1 expiry disables ttl passing 0 means the redis side is not used as redis does not support ttl 0

By default the redis key will the fully qualified function name followed by args

"redimize.core_test$slowly:(-1)"

You can pass an optional prefix if you need to disambiguate

(:require [redimize.core :as red])

(defn slowly [n]
  (Thread/sleep 5000)
  n)
  
(def conn {:host "127.0.0.1", :port 6379})

(def memoized-no-key (red/dual-memo conn slowly :expire -1))
(def memoized-test   (red/dual-memo conn slowly :keyprefix "test-1" :expire -1))
(def memoized-test1  (red/dual-memo conn slowly :keypreifx "test09" :expire 9))
(def memoized-test2  (red/dual-memo conn slowly :keyprefix "test60" :expire 60))
(def memoized-1-hour (red/dual-memo conn slowly))


(time (prn (memoized-no-prefix -1)))
(time (prn (memoized-test -1)))
(time (prn (memoized-test1 9)))
(time (prn (memoized-test2 60)))
(time (prn (memoized-1-hour 60)))
