apsaracache's Introduction

⚠️ This project is archived

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 vanilla version.

Building ApsaraCache

It is as simple as:

% make

Running ApsaraCache

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

   protocol  memcache

to redis.conf.

To run ApsaraCache with the default configuration just type:

% cd src
% ./redis-server

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

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 debug

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

Playing with ApsaraCache in Redis mode

You can use redis-cli to play with ApsaraCache. Start a redis-server instance, then in another terminal try the following:

% cd src
% ./redis-cli
redis> ping
PONG
redis> set foo bar
OK
redis> get foo
"bar"
redis> incr mycounter
(integer) 1
redis> incr mycounter
(integer) 2
redis>

You can find the list of all the available commands at http://redis.io/commands.

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  

Enjoy!

aofsplit逻辑漏洞

aofSplit>openAppendOnly

如果openAppendOnly失败,则appendonly被关闭;此时无法执行写命令,并且即使磁盘恢复正常server也无法自动恢复。

为什么不直接向Redis提交PR

看描述是基于Redis的拓展和优化,在存在Redis的情况下,为什么要选择重新造一个轮子,而不是完善现有的Redis?
公司是出于什么方面的考量呢?

Is the project dead?

I haven't seen new release for long time, so would be great to know the plans with this.
Thanks
