Introduction中文
Pika is a persistent huge storage service , compatible with the vast majority of redis interfaces (details), including string, hash, list, zset, set and management interfaces. With the huge amount of data stored, redis may suffer for a capacity bottleneck, and pika was born for solving it. Except huge storage capacity, pika also support master-slave mode by slaveof command, including full and partial synchronization. You can alse use pika in twemproxy or codis(pika has supported data migration in codis,thanks left2right) for distributed Redis solution
- huge storage capacity
- compatible with redis interface, you can migrate to pika easily
- support master-slave mode (slaveof)
- various management interfaces
- optimize engine nemo to improve list performance
- snappy - a library for fast data compression
- protobuf - google protobuf library
- glog - google log library
Upgrade your gcc to version at least 4.8 to get C++11 support.
-
linux - Centos 5&6

linux - Ubuntu
If it comes to some missing libs, install them according to the prompts and retry it.
Upgrade your gcc to version at least 4.8 to get C++11 support.
Get source code recursive, then pika will pull all submodules
git clone https://github.com/Qihoo360/pika.git
Then compile pika
make
./output/bin/pika -c ./conf/pika.conf

On different pika worker threads, we test the pika max QPS.
pika db_size : 800G
value : 128bytes
CPU is not binded
Description : Horizontal axis is the pika threads number; Vertical axis is the QPS. Pika value size is 128bytes. set3/get7 means 30% set and 70% get.
The best pika work threads number is 20-24.
On the pika optimal worker threads, we test the pika round-trip time.
