Mem

KV cache with TTL, Replacement and Persistence support

Usage

1. define your cache module

   defmodule Cache do
     use Mem,
       worker_number:      2,       # (optional, default: 2) how many processes in worker pool
       default_ttl:        300,     # (optional, default: nil) default expire seconds for set/2
   
       maxmemory_size:     "1000M", # (optional, default: nil) max memory used, support such format: [1000, "10k", "1GB", "1000 K"]
       maxmemory_strategy: :lru,    # ([:lru, :ttl, :fifo]) strategy for cleaning memory
       persistence:        false    # (optional, default: false) whether enable persistence
   
   end
   

2. add this module to supervisor

   defmodule MyApp.Supervisor do
     use Supervisor
   
     def start_link do
       Supervisor.start_link(__MODULE__, [])
     end
   
     def init([]) do
       [ Cache.child_spec,
       ] |> supervise(strategy: :one_for_one)
     end
   
   end
   

3. just use it like redis

   Cache.set(:a, 1)
   Cache.inc(:a, 2)
   Cache.set(:b, 2, 200)
   Cache.get(:a)
   Cache.expire(:a, 200)
   Cache.ttl(:a)
   Cache.del(:b)
   Cache.flush
   
   Cache.hset(:c, :a, 2)
   Cache.hget(:c, :a)
   
   Cache.memory_used()
