MMKV for Android

MMKV is an efficient, small, easy-to-use mobile key-value storage framework used in the WeChat application. It's currently available on both Android, iOS/macOS, Windows and POSIX.

Performance

We test MMKV side-by-side with SharedPreferences & SQLite, repeating each operation 1k times. The result is in the chart below. The benchmark code can be found in Android/MMKV/mmkvdemo/ project.

Baseline Performance
As we can see, MMKV beats SharedPreferences & SQLite on writing values, while equals or outranges them on reading values.
