An always up-to-date local memory hash for Ruby and Redis
Redis Replicated Hash is a simple Ruby library for synchronizing a local memory hash against a Redis server.
To achieve this, Redis replication is implemented.
Simply create an instance of RedisReplicatedHash optionally passing the hostname and port of the server. The third parameter is a boolean indicating whether the call should block until the database is fully loaded into memory.
require './redis-replicated-hash'
replicated_hash = RedisReplicatedHash.new
puts "Replicated hash is running, and probably synchronizing right now!"
puts "Enter the key to retrieve:"
while line = gets
puts "Retrieved value is:"
p replicated_hash.keys[line[0..-2]]
end
