LevelDB

LevelDB is a fast key-value storage library written at Google that provides an ordered mapping from string keys to string values. Created by Google

Free Open Source
Mac
Windows
Linux
Android

LevelDB stores keys and values in arbitrary byte arrays, and data is sorted by key. It supports batching writes, forward and backward iteration, and compression of the data via Google's Snappy compression library.

LevelDB is not a SQL database. Like other NoSQL and Dbm stores, it does not have a relational data model and it does not support SQL queries.

Features

- Keys and values are arbitrary byte arrays.
- Data is stored sorted by key.
- Callers can provide a custom comparison function to override the sort order.
- The basic operations are Put(key,value), Get(key), Delete(key).
- Multiple changes can be made in one atomic batch.
- Users can create a transient snapshot to get a consistent view of data.
- Forward and backward iteration is supported over the data.
- Data is automatically compressed using the Snappy compression library.
- External activity (file system operations etc.) is relayed through a virtual interface so users can customize the operating system interactions.
