LruCache

Simple LRU Cache, implemented with ets.

Installation

The package can be installed as:

1. Add lru_cache to your list of dependencies in mix.exs:

defdepsdo[{:lru_cache,"~> 0.1.0"}]end

2. Ensure lru_cache is started before your application:

defapplicationdo[applications: [:lru_cache]]end

Using

Typically you want to start the cache from a supervisor:

worker(LruCache,[:my_cache,10])

Or starting it manually:

LruCache.start_link(:my_cache,10)

The resulting process and ets table will be registered under this alias. Now you can use the cache as follows:

LruCache.put(:my_cache,"id","value")LruCache.get(:my_cache,"id")LruCache.get(:my_cache,"id",touch=false)LruCache.update(:my_cache,"id","new_value",touch=false)LruCache.delete(:my_cache,"id")
