Installation is straight-forward: just add the gem to your
gem "all_futures", "~> 1.0"
All Futures relies on Redis via the Kredis gem. Make sure that you have a Redis server running and that you have followed the Kredis installation instructions.
If possible, consider running a Redis instance specifically for your All Futures instances. This will allow maximum flexibility and removes any ambiguity about the purpose of the keys.
All Futures is designed to create Redis keys on an as-needed basis. No attempt is made to clear keys, as there is an expectation that you will set an eviction policy which will remove old keys to make room for new ones.
allkeys-lru policy is likely your best bet for an All Futures configuration.
