PikiwiDB

中文

A C++11 implementation of Redis Server, use Leveldb for persist storage.(not including cluster yet)

Requirements

  • C++11
  • Linux or OS X

Support module for write your own extensions

PikiwiDB supports module now, still in progress, much work to do. I added three commands(ldel, skeys, hgets) for demonstration.

Persistence: Not limited to memory

Leveldb can be configured as backend for PikiwiDB.

Fully compatible with redis

You can test PikiwiDB with redis-cli, redis-benchmark, or use redis as master with PikiwiDB as slave or conversely, it also can work with redis sentinel.

High Performance

  • PikiwiDB is approximately 20-25% faster than redis if run benchmark with pipeline requests(set -P = 50 or higher).
  • Average 80K requests per seconds for write, and 90K requests per seconds for read.
  • Before run test, please ensure that std::list::size() is O(1), obey the C++11 standards.

Run this command, compare with redis use pipeline commands, try it.

./redis-benchmark -q -n 1000000 -P 50 -c 50
