Elastic, scalable, highly available, secure cloud-based key/value store.
Last updated 20 February 2019
IronCache is an elastic, scalable, highly available, persistent and secure cloud based key/value store. IronCache grows with you on demand, doesn’t evict items (they only expire), and ensures you’ll never need to rebuild your cache. It’s great for persistent and reliable incrementors/counters, and can be accessed through an easy to use REST interface or memcached interface. Used it for short term persistence and long term storage without worrying about losing data.
You also have full visibility into your caches and usage with the Iron.io user interface:
It’s quick and easy to get IronCache set up and running on Heroku; you just need to install the IronCache addon. You can do this with the
$ heroku addons:create iron_cache:developer -----> Adding iron_cache to cold-winter-5462... done, v10 (free)
This will add the developer level addon for IronCache, which will let you test the add-on and play around a bit.
There are other levels of the addon, as well. We recommend you upgrade before you use IronCache in production.
First, install the Ruby gem:
$ gem install iron_cache Fetching: iron_cache-1.4.0.gem (100%) Successfully installed iron_cache-1.4.0
If you’re building for a Rails application or anything that uses Bundler, add the following to your Gemfile:
This is for the Ruby client, but all clients have the same operations. See the docs for your particular language.
require 'iron_cache' # Create an IronCache::Client object @ironcache = IronCache::Client.new # Get a cache (if it doesn't exist, it will be created when you first post an item @cache = @ironcache.cache("my_cache") # Put an item @cache.put("mykey", "hello world!") # Get an item item = @cache.get("mykey") p item.value # Delete an item item.delete # or @cache.delete("mykey") # Increment an item in the cache item = @cache.increment("mycounter", 1) p item
Install with pip/easy_install
iron_cache_python is available in the Python Package Index as “iron_cache”. This means you can run
pip install iron_cache
easy_install iron_cache from your command line to download iron_cache_python and all its dependencies.
Install from source
You can also download the source from Github. Once you have the source, you can run
python setup.py install
from the directory containing the source code to install iron_cache_python.
Note: You will need the iron_core_python module for iron_cache_python to function.
from iron_cache import * # Create an client object cache = IronCache() # Put an item cache.put(cache="test_cache", key="mykey", value="Hello IronCache!") # Get an item item = cache.get(cache="test_cache", key="mykey") print item.value # Delete an item cache.delete(cache="test_cache", key="mykey") # Increment an item in the cache cache.increment(cache="test_cache", key="mykey", amount=10)
Download iron_cache.phar from from Github and require it in your code:
<?php require_once "phar://iron_cache.phar";
<?php require_once "phar://iron_cache.phar"; # Create a client object $cache = new IronCache(); $cache->setCacheName('my_cache'); # Put an item $cache->put("mykey", "hello world!"); # Get an item $item = $cache->get("mykey"); echo $item->value # Delete a message (you must delete a message when you're done with it or it will go back on the queue after a timeout $cache->delete("mykey"); # Increment an item in the cache $cache->increment("mykey", 1);
