LevelDB: A Fast Persistent Key-Value Store

“LevelDB is a fast key-value storage engine written at Google
that provides an ordered mapping from string keys to string values.
We are pleased to announce that we are open sourcing LevelDB under
a BSD-style license.

“LevelDB is a C++ library that can be used in many contexts. For
example, LevelDB may be used by a web browser to store a cache of
recently accessed web pages, or by an operating system to store the
list of installed packages and package dependencies, or by an
application to store user preference settings. We designed LevelDB
to also be useful as a building block for higher-level storage
systems. Upcoming versions of the Chrome browser include an
implementation of the IndexedDB HTML5 API that is built on top of
LevelDB.
