Scylla has advantage and amazing features. If Redis build on the top of Scylla, it has the above features automatically. It's achived great progress in cluster master managment, data persistence, failover and replication. The benefits to the users are easy to use and develop in their production environment, and taking avantages of Scylla. Using the Ragel to parse the Redis request, server abtains the command name and the parameters from the request, invokes the Scylla's internal API to read and write the data, then replies to client.
