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

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.
