Pogocache::Ruby

Use pogocache as an in-memory store in Ruby. This gem embeds pogocache as a C extension and provides the class Pogocache::Cacheto interact with it. The goal is to provide a faster, more lightweight alternative to ActiveSupport::Cache::MemoryStore. The state of this project is pre release but functional. Feedback is welcome.

Features

Fast caching operations
Low memory footprint
Arbitrary objects as keys and values
Linux and MacOS support

Threading

This gem relies on the GVL when used in a multi-threaded context. It does not free the lock before any operation.

Usage

bundle add pogocache-ruby

require 'pogocache-ruby'

cache = Pogocache::Cache.new

cache.set("value1", "string 1")
cache[:value2] = { hash_key: "value" }

cache.fetch(:value2)
# => {hash_key: "value"}
cache["value1"]
# => "string 1"

See pogocache_spec.rb and pogocache.h for details.
