Pika

Build Status

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

Feature

  • huge storage capacity
  • compatible with redis interface, you can migrate to pika easily
  • support master-slave mode (slaveof)
  • various management interfaces

Quickstart and Try

You can try to use our pre-build binary versions. For now, only Centos5 and Centos6 are supported. The binary ones can be found at the release page which are called pikaX.Y.Z_centosK_bin.tar.gz.

# 1. unzip file
tar zxf pikaX.Y.Z_centosK_bin.tar.gz
# 2. change working directory to output
#   note: we should in this directory, caz the RPATH is ./lib;
cd output
# 3. run pika:
./bin/pika -c conf/pika.conf

For developer

RoadMap

  • optimize engine nemo to improve list performance

Dependencies

  • snappy - a library for fast data compression
  • zlib - a library for fast data compression
  • bzips - 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.

Supported platforms

  • linux - Centos 5&6

  • linux - Ubuntu

If it comes to some missing libs, install them according to the prompts and retry it.

Compile

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 --recursive https://github.com/baotiao/pika.git

Then compile pika

make __REL=1

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

test environment

2 same hardware server, one for running pika, the other for running redis-benchmark

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

test interfaces

Set, Get

test method

run pika with 16 work threads, run redis-benchmark on another server as follow: 
./redis-benchmark -h ... -p ... -n 1000000000 -t set,get -r 10000000000 -c 120 -d 200
execute 1 billion Set and 1 billion Get commands altogether
