# MMKV: Fast persistence key-value engine on memory mapped file

[![Build Status](https://travis-ci.org/yinqiwen/mmkv.svg?branch=master)](https://travis-ci.org/yinqiwen/mmkv)    

MMKV is a BSD licensed, fast persistence key-value engine built on memory mapped file.

 

## Building MMKV

It only can be compiled on Linux now.   

To build the whole project, just type `make` to compile lib & tests.   

It should compile to a static library and test executable in `src` directory, such as libmmkv.a, mmkv-test etc. 

MMKV depends on `boost`, if the `boost` headers could not found by the compiler defaulty, set env `BOOST_INC` first.

	

	BOOST_INC=/boost_headers/include make

## Features

- Designed for application servers wanting to store many complex data sturctures on locally in shared memory.

- Persistence Key-value store, the value could be any complex data structure

- Multiple processes concurrency suported

- Most redis data stuctures&api suported

- Custom POD type supported.

- Very fast, which have similar performance compared to same data structure in memory.

## Warnings

- Application/System crashes may corrupt the whole data store if it doing write operations. 

## Status

- Still in development, but already used in a real project which need a very fast cache for multiple processes.
