A Fast Key-Value Storage Engine Written at Google
LevelDB is a fast key-value storage engine written at Google that provides an ordered mapping from string keys to string values. Google has recently announced that they 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.
