What is it all about?
LevelDB is a fast key-value storage library written at Google that provides an ordered mapping from string keys to string values
Key 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.
