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

• C++11
• Linux or OS X

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

Leveldb can be configured as backend for PikiwiDB.

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.

• 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
