#Pika
##Introduction [中文] (https://github.com/Qihoo360/pika/blob/master/README_CN.md)
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
##Feature
- huge storage capacity
- compatible with redis interface, you can migrate to pika easily
- support master-slave mode (slaveof)
- various management interfaces
##Install
1.Install snappy-devel bz2 libzip-dev libsnappy-dev libprotobuf-dev libevent-dev protobuf-compiler libgoogle-glog-dev protobuf-devel libevent-devel bzip2-devel libbz2-dev zlib-devel etc on you compiling host(if alreadly installed, ignore it); using "yum install" on centos system("apt-get install" on ubuntu system) is ok. If on CentOS system, run the following commands:
yum install snappy-devel bz2 libzip-dev libsnappy-dev libprotobuf-dev libevent-dev protobuf-compiler libgoogle-glog-dev protobuf-devel libevent-devel bzip2-devel libbz2-dev zlib-devel
2.Install g++(if installed, skip). Similarly, just using "yum install" on the CentOS(apt-get on Ubuntu) is ok:
yum install gcc-c++
3.If your gcc's version is below 4.7, then change it to the 4.7 temporary. For CentOS system, run the flowing commands:
a. sudo wget -O /etc/yum.repos.d/slc6-devtoolset.repo http://linuxsoft.cern.ch/cern/devtoolset/slc6-devtoolset.repo
b. yum install --nogpgcheck devtoolset-1.1
c. scl enable devtoolset-1.1 bash
4.Fetch the source code:
a. git clone [email protected]:Qihoo360/pika
b. cd pika
5.Get the third party dependencies:
a. git submodule init
b. git submodule update
6.Compile:
make __REL=1
If it comes to some missing libs, install them according to the prompts and retry it.
##Usage
./output/bin/pika -c ./conf/pika.conf
If failed, move pika source/lib/_VERSION/lib/ to the rpath defined in Makefile and relanch.
cp PIKA_SOURCE/lib/_VERSION/* RPATH
The PIKA_SOURCE stands for pika source code's root directory;
The __VERSION represents the OS's version, such as 6.2, 5.4...
The RPATH is defined in pika's Makefile
##Performance
Server Info:
CPU: 24 Cores, Intel(R) Xeon(R) CPU E5-2630 v2 @ 2.60GHz
MEM: 165157944 kB
OS: CentOS release 6.2 (Final)
NETWORK CARD: Intel Corporation I350 Gigabit Network Connection
Client Info:
Same as Server
Test:
Pika run with 18 worker threads, and we test it using 40 client;
1. Write Performance:
Client push data by set, hset, lpush, zadd, sadd, each interface has 10000 key range;
result: 110000 qps
2. Read Performance:
Client pull data by get, hget, lindex, zscore, smembers, 25000000 keys stored in pika and each interface has 5000000 key range
result: 170000 qps
