What is ApsaraCache ?

ApsaraCache is based on the Redis official release 4.0 and has many features and performance enhancements. ApsaraCache has proven to be very stable and efficient in production environment.

There are many features in ApsaraCache, the following two are included in this release and the other features will be gradually released in the subsequent, so stay tuned.

  • ApsaraCache supports two main protocols of Memcached: the classic ASCII, and the newer binary. You can use ApsaraCache just as Memcached, and no client code need to be modified. You can persist your data by using ApsaraCache in Memcached mode just like Redis.
  • In short connection scenario, ApsaraCache makes 30% performance increase compared with the open source version.

Running ApsaraCache

In default, ApsaraCache run in Redis mode. If you want ApsaraCache to run in Memcached mode, just add option

   protocol  memcache
Copy the code

to redis.conf.

To run ApsaraCache with the default configuration just type:

% cd src
% ./redis-server
Copy the code

If you want to provide your redis.conf, you have to run it using an additional parameter (the path of the configuration file):

% cd src
% ./redis-server /path/to/redis.conf
Copy the code

It is possible to alter the ApsaraCache configuration by passing parameters directly as options using the command line. Examples:

/redis-server --port 9999 --slaveof 127.0.0.1 6379%./redis-server /etc/redis/6379.conf --loglevel debugCopy the code

All the options in redis.conf are also supported as options using the command line, with exactly the same name.

Playing with ApsaraCache in Memcached mode

You can use telnet to visit ApsaraCache(telnet use the classic ASCII protocol).

 % telnet your-host your-port(usually 11211)
 
   set key 10 3600 2
   ok
   STORED
   get key
   VALUE key 10 2
   ok
   END  
Copy the code

Enjoy!
