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