Redis SSDB Proxy

The Redis SSDB Proxy that read from redis(or ssdb) write to both use for redis <=> ssdb migration on production

Add this line to your application's Gemfile:

gem 'redis-ssdb-proxy'

And then execute:

$ bundle

Or install it yourself as:

$ gem install redis-ssdb-proxy

If you want migrate redis data to SSDB the below code will write data to both of redis and ssdb and read from redis only

The options ssdb: :slave tells Proxy which redis-client is connected to the ssdb server which means Proxy will be delegating the unsupport data-structure (set) of SSDB to supported(zset)

ssdb = Redis.new(host: 'localhost', port: '8888')
redis = Redis.new(host: 'localhost', port: '6379')

$redis = RedisSsdbProxy.new(master: redis, slave: ssdb, ssdb: :slave)

$redis.set(:quotes, 'May the force be with you') # set to both
$redis.get(:quotes) # read from master (redis)
# => May the force be with you

When the data migrated the below line code will being prepare for the rollback

$redis = RedisSsdbProxy.new(master: ssdb, slave: redis, ssdb: :master)
